"Ambica Steels specializes in the production of 17-4 steels (also known as 1.4542 Bar and AISI 630). This is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines a very high strength, hardness (up to 572°F / 300°C), and corrosion resistance. Mechanical properties can be optimized for various heat treatments. Very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved. Ambica Steels offers various heat treatments in this grade like – Solution Annealed, H900, H925, H1025, H1075, H1150, H1150D, H1150M, P800, P930, P960, P1070 etc with both Air & Oil quenching."

Finding the perfect type of stainless steel does not have to be a complicated process. Stainless steel has a variety of benefits. For example, its chromium content allows stainless steel to resist the formation of ferric oxide, while its nitrogen content prevents pitting. Stainless steel is also heat resistant, non-reactive, easy to clean, versatile, and highly desirable, with its ability to be recycled.
