2. Shock-resisting steel - Wikipedia

   en.wikipedia.org/wiki/Shock-resisting_steel

   SVCM steel is a kind of shock-resisting steel. [5] SVCM steel is an alloy of carbon, silicon, chromium, magnesium, nickel, molybdenum and lead. [6] SVCM+ in addition is quenched and tempered achieving a high hardness (HRC 59). [6] SCVM+ has better torsional properties than chromium-vanadium steel (Cr-V). [7]

3. Steel grades - Wikipedia

   In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications. The number is in the following format: x.yyzz(zz)

   A6, a grade of tool steel which air-hardens at a relatively low temperature (approximately the same temperature as oil-hardening grades) and is dimensionally stable. Therefore, it is commonly used for dies, forming tools, and gauges that do not require extreme wear resistance but do need high stability. [4] A7 [5] tool steel is an A7 type air ...

   Tools and workpieces may also cause damage when dropped on the surface plate. Also, damage can be caused when swarf and other debris have not been removed. This will result in erroneous measurements. Damage to the plate can be corrected only by resurfacing, which requires specialised techniques and equipment depending on the grade of the plate.

   UNS K11547 is T2 tool steel; UNS S17400 is ASTM grade 630, Cr-Ni 17-4PH precipitation hardened stainless steel; UNS S30400 is SAE 304, Cr/Ni 18/10, Euronorm 1.4301 stainless steel; UNS S31600 is SAE 316; UNS S31603 is 316L, a low carbon version of 316. The digits "03" were assigned since the maximum allowed carbon content is 0.03%; UNS C90300 ...
