1.3243 (Electro Slag Remelted, ESR)

3243 Steel ESR (High Speed Steel, HSS) Properties

3243 steel is a high speed steel containing %5 Cobalt element in its structure. 3343 steel The biggest feature that distinguishes it from 'is that it can maintain its hardness at high temperatures. It is suitable for EDM cutting, welding, PVD, and CVD coating.

Our company in stocks 3243 steelThey are ESR, that is, they are melted twice to produce a structurally cleaner steel. This allows it to have higher toughness. It reduces your cost by giving higher performance.
