10 10 is stainless steel food grade?

S4 10 10 is not food grade stainless steel.

1Cr13 (s 41010) belongs to martensitic stainless steel, corresponding to the new national standard number 12Cr 13.

1cr 13(s 4 10 10)? Implementation standard: GB /T 20878-2007 (brand and chemical composition of stainless steel and heat-resistant steel).

1cr 13(s 4 10 10)? It has high hardness, toughness, good corrosion resistance, thermal strength and cold deformation performance, and good shock absorption. Tempering at high or low temperature is required, but tempering at 370-560℃ should be avoided. Weakly corrosive medium resistant and load-bearing parts, such as turbine blades, hydraulic pressure valves, bolts, nuts, etc. , mainly used for parts that require high toughness, certain rust resistance and bear impact load, such as tools, blades, fasteners, hydraulic valves, hot cracking sulfur corrosion-resistant equipment, etc. It can also be used for equipment and components with weak corrosion resistance at room temperature.

The chemical composition of1Cr13 (S 41010) is as follows:
