CK35 Stainless Steel Properties, Composition & Equivalent

CK35 ASTM A743    Grade:DIN 17200      Alloy Family: Austenitic Stainless Steel      Equivalent: 1035 stainless steel

What is CK35 Stainless Steel ?

It is a high-quality carbon structural steel (GB / t699-2015).

It has good plasticity and proper strength, good process performance, and fair welding performance. It is used in normalizing and quenching and tempering conditions.

It is used in the manufacture of various forgings and hot-pressed parts, cold drawn and upset steel, steel pipe, parts in mechanical manufacturing.

CK35 Stainless Steel VS CK45 Stainless Steel

CK45 is a high-quality carbon structural steel, its strength is 61, HRC is 48-55, which is more used in machinery; CK35 is also a high-quality carbon structural steel, but its strength is only 54, HRC is 38-45.

The difference between them can be distinguished from the spark. The spark with low carbon content has a drooping tail and a slightly dark color. Sometimes there are gun tip tail flowers. The amount of flowers is not much and the awn line is thick. CK45 has a straight tail, a bifurcated streamline at the tip, a large injection force, and a large amount of flowers

The carbon content  is higher in CK45 stainless steel, of course, CK45 is harder.
