Is S7 stainless?
Both AISI 304 stainless steel and SAE-AISI S7 steel are iron alloys. They have 74% of their average alloy composition in common.
How strong is S7 tool steel?
S7 tool steel is a shock-resistant grade containing high impact properties. Its charpy (a test that measures the impact strength) is over 200 ft-lb….What is S7 Tool Steel?
Carbon | 0.50 |
---|---|
Molybdenum | 1.40 |
Silicon | 0.25 |
Manganese | 0.70 |
How do you harden S7 steel?
S7 should be preheated at 1200 to 1300°F and raised to the hardening temperature of 1725°F, holding at temperature for one hour for each inch of greatest cross-section. Sections 2-1/2-in. or less should be quenched in still air. Upon reaching 150°F, the piece should be tempered without delay.
What is S7 steel made of?
Chemical Composition
Element | Content (%) |
---|---|
Iron, Fe | 93.85 |
Carbon, C | 0.45-0.55 |
Manganese, Mn | 0.20-0.80 |
Silicon, Si | 0.20-1.00 |
Can you forge S7 steel?
S7 has medium hot work characteristics, making it a tool steel used for both cold and warm shock applications, as well as molds that require high hardness. 1. Forging: Preheat 1200°-1300°F. Forge at 2000°-2050°F.
Can you flame harden S7?
S7 can be flame hardened with out much difficulty. Easy air quench and dimensionally stable. Though a controlled atmosphere oven is to be preferred. I use it for punches, shearing blades of various types, and other parts that need to withstand a repeated good whack.
Can tool steel rust?
Precipitation hardening steel is extremely corrosion resistant. This material also requires no additional hardening and tempering by the customer because it already has a work hardness of 38-42 HRC after hot forming and heat treatment. It also has high strength and toughness.
