1.2550 steel is a steel grade formed by adding a certain amount of tungsten on the basis of chromium silicon steel, because tungsten helps to preserve the finer grains during quenching, and obtains higher toughness in the tempered state.

Typical application examples
① Suitable for low-deformation steel and Cr12 series steel that are made of carbon steel with insufficient load-bearing capacity, and are made of oil-quenched steel, which are prone to brittleness, but are made of high-speed steel or high-strength steel, and are uneconomical and high-wear molds.
② This steel can be used when the main failure mode is wear and collapse.
③ Suitable for manufacturing scissors, slicing punches, etc.
④ It can be used for punching dies, press dies, casting finishing tools, pneumatic chisels, etc. that work under heavy loads.
⑤ As a hot processing steel, it can produce screws and hot riveting punches.
⑥ High temperature die-cast light alloy head.
⑦ Hot forging die, etc.
