ASTM A36 is a common mild steel(carbon structure steel grade). It is widely used in morden industry owning to its cheapest rolling cost and easiest welding. SMA400BP railway vehicles steel, ASTM A36 mild steel is equivalent to grade Q235B under Chinese steel standard, grade S235JR under European steel standard EN 10025-2, grade SS400 in Japanese steel standard. These mild steel plates and sections are commonly bolted and riveted in structural applications.

After quenching and tempering, 40Cr alloy steel plate and SMA400BP railway vehicles steel sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel SMA400BP railway vehicles steel is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.
