What is CA15 Stainless Steel？
CA15 stainless steel is a kind of martensitic stainless steel with good corrosion resistance and machinability.
It is is often used to make blades, tableware and valves. Compared with other stainless steel materials, it has higher strength and better safety performance, so it is widely used in some other industries.
It is equivalent to 410 stainless steel

410 stainless steel
410 stainless steel is produced according to the American ASTM standard, which is equivalent to China’s 1Cr13 stainless steel, ASTM S41000. Carbon 0.15%, chromium 13%. Carbon 0.15%, chromium 13%
410 stainless steel: with good corrosion resistance, machinability, general-purpose blade, valve. Heat treatment of 410 stainless steel: solution treatment (℃) 800-900 slow cooling or 750 fast cooling.
What is the difference between 316 vs 410 stainless steel ?
Compared with 410 stainless steel, 316 stainless steel has stronger corrosion resistance and weldability, and is used more widely. But it is also more expensive. 316 stainless steel in rust and corrosion resistance is far better than 410 stainless steel, but in some special occasions, 316 stainless steel can not replace 410 stainless steel
