Threads Per Inch (TPI): used to measure inch fasteners — how many threads are present in an inch of the thread length ... number, the closer it is to 1/4 inch.

It is a chromium-nickel-molybdenum stainless with low carbon (0.08%) content. The low carbon content combined with high chromium/nickel/molybdenum amount results in soft material with high resistance to machining and a low machinability rating of 40%.The molybdenum gives 316 better corrosion-resistant properties than 304 stainless, notably higher resistance to pitting and crevice corrosion in chloride environments.It is mainly used in food preparation equipment, laboratory devices, chemical containers, fasteners, and heaf-exchangers.316 stainless has several variations:NameExplanationMachinability (%)316 (Regular)40%316LL stands for Low Carbon. The carbon amount is 0.03%, vs 0.08% in the other 316 alloys. It is mainly used in pulp-handling equipment, rubber production, and high-temperature equipment.35%316LVMVM stands for Vacuum Melt required to achieve high-level micro-cleanliness. This alloy is mostly used in medical applications such as bone screws35%316NN stands for Nitrogen. It is produced with 0.10–0.16% nitrogen, which improves resistance against pitting and crevice corrosion. 316N is mainly used for chemical handling accessories.~40%316FF stands for Freecut. It has a minimum content of 0.1% of Sulfur, which enhances its machinability. It is primarily used on Swiss-type Machines (Screw Machines) when productivity is a crucial factor.~50%The main characteristic of austenitic stainless is the low carbon content combined with high chromium/nickel content. The result is a ductile material with high resistance to machining. Because of its softness, you must use a sharp and positive cutting edge. One of the biggest problems in machining stainless steel 316 is the forming of notch wear at the depth of the cut line, which results in a burr forming on the workpiece. The best method to avoid notch wear is to constantly change the machining depth.Summery:For general Turning of Stainless Steel 316 at stable conditions use a grade with a Semi Hard substrate and CVD coating.In case you are running at a cutting speed that is lower than 390 SFM (120 m/min), it is better to use a grade with aSemi Hard substrate and PVD coating.For general Milling use a grade with a Semi Hard substrate and PVD coating.For detailed carbide grades recommendations, check the Below Chart, or use the Grades Wizrad.Recommended Cutting speed range for turning at stable conditions is 490 - 660 [SFM] / 150 - 200 [m/min].Recommended Cutting speed range for milling with stable clamping and short overhang is 310 - 410 [SFM] / 95 - 125 [m/min]For detailed cutting speed recomendations, check the Below Table, or use our Speed and Feed Calculator.Equivalent International Designations for Stainless Steel 316StandardNamesae316wnr1.4401dinX5CrNiMo17-13-3bs316S33, 58Jss2343anforZ6CND19.12.03uniX5CrNiMo1713unfF.3543js1SUS316Chemical Composition for Stainless Steel 316ElementAmountChromium (Cr)17%Nickel (Ni)13%Manganese (Mn)2.00%Molybdenum (Mo)1.50%Silicon (Si)0.75%Carbon (C)0.08%Phosphorus (P)0.04%Sulfur (S)0.03%Cutting Speeds Recomendations for Stainless Steel 316* Click on the speeds below for higher precision in specific conditions!ApplicationVc (m/min)Vc (SFM)Turning150-200490-660Milling95-125310-410Parting60-80200-260Grooving90-120300-390Drilling45-60150-200Important!

316 stainless has several variations:NameExplanationMachinability (%)316 (Regular)40%316LL stands for Low Carbon. The carbon amount is 0.03%, vs 0.08% in the other 316 alloys. It is mainly used in pulp-handling equipment, rubber production, and high-temperature equipment.35%316LVMVM stands for Vacuum Melt required to achieve high-level micro-cleanliness. This alloy is mostly used in medical applications such as bone screws35%316NN stands for Nitrogen. It is produced with 0.10–0.16% nitrogen, which improves resistance against pitting and crevice corrosion. 316N is mainly used for chemical handling accessories.~40%316FF stands for Freecut. It has a minimum content of 0.1% of Sulfur, which enhances its machinability. It is primarily used on Swiss-type Machines (Screw Machines) when productivity is a crucial factor.~50%The main characteristic of austenitic stainless is the low carbon content combined with high chromium/nickel content. The result is a ductile material with high resistance to machining. Because of its softness, you must use a sharp and positive cutting edge.

Stainless Steel 316 is an austenitic stainless steel alloy with 17% chromium and 13% nickel. It is the most popular stainless steel when high corrosion resistance is required.It is a chromium-nickel-molybdenum stainless with low carbon (0.08%) content. The low carbon content combined with high chromium/nickel/molybdenum amount results in soft material with high resistance to machining and a low machinability rating of 40%.The molybdenum gives 316 better corrosion-resistant properties than 304 stainless, notably higher resistance to pitting and crevice corrosion in chloride environments.It is mainly used in food preparation equipment, laboratory devices, chemical containers, fasteners, and heaf-exchangers.316 stainless has several variations:NameExplanationMachinability (%)316 (Regular)40%316LL stands for Low Carbon. The carbon amount is 0.03%, vs 0.08% in the other 316 alloys. It is mainly used in pulp-handling equipment, rubber production, and high-temperature equipment.35%316LVMVM stands for Vacuum Melt required to achieve high-level micro-cleanliness. This alloy is mostly used in medical applications such as bone screws35%316NN stands for Nitrogen. It is produced with 0.10–0.16% nitrogen, which improves resistance against pitting and crevice corrosion. 316N is mainly used for chemical handling accessories.~40%316FF stands for Freecut. It has a minimum content of 0.1% of Sulfur, which enhances its machinability. It is primarily used on Swiss-type Machines (Screw Machines) when productivity is a crucial factor.~50%The main characteristic of austenitic stainless is the low carbon content combined with high chromium/nickel content. The result is a ductile material with high resistance to machining. Because of its softness, you must use a sharp and positive cutting edge. One of the biggest problems in machining stainless steel 316 is the forming of notch wear at the depth of the cut line, which results in a burr forming on the workpiece. The best method to avoid notch wear is to constantly change the machining depth.Summery:For general Turning of Stainless Steel 316 at stable conditions use a grade with a Semi Hard substrate and CVD coating.In case you are running at a cutting speed that is lower than 390 SFM (120 m/min), it is better to use a grade with aSemi Hard substrate and PVD coating.For general Milling use a grade with a Semi Hard substrate and PVD coating.For detailed carbide grades recommendations, check the Below Chart, or use the Grades Wizrad.Recommended Cutting speed range for turning at stable conditions is 490 - 660 [SFM] / 150 - 200 [m/min].Recommended Cutting speed range for milling with stable clamping and short overhang is 310 - 410 [SFM] / 95 - 125 [m/min]For detailed cutting speed recomendations, check the Below Table, or use our Speed and Feed Calculator.Equivalent International Designations for Stainless Steel 316StandardNamesae316wnr1.4401dinX5CrNiMo17-13-3bs316S33, 58Jss2343anforZ6CND19.12.03uniX5CrNiMo1713unfF.3543js1SUS316Chemical Composition for Stainless Steel 316ElementAmountChromium (Cr)17%Nickel (Ni)13%Manganese (Mn)2.00%Molybdenum (Mo)1.50%Silicon (Si)0.75%Carbon (C)0.08%Phosphorus (P)0.04%Sulfur (S)0.03%Cutting Speeds Recomendations for Stainless Steel 316* Click on the speeds below for higher precision in specific conditions!ApplicationVc (m/min)Vc (SFM)Turning150-200490-660Milling95-125310-410Parting60-80200-260Grooving90-120300-390Drilling45-60150-200Important!
