1. Common carbon structural steel: carbon structural steel is divided into 5 grades according to the yield strength of steel: Q195, Q215, Q235, Q255, Q275. Each brand is divided into A, B, C and D grades due to its different quality. Q195, Q215, Q235 good plasticity, can be rolled into steel plate, steel bar, steel pipe, etc. Q255, Q275 can be rolled into steel, steel, etc.
2. High quality carbon structural steel: steel number is expressed by the average mass thousandth fraction of carbon element content. Such as 20#, 45#, etc. Application: Mainly used for manufacturing various machine parts.
3. Carbon tool steel: steel grade is expressed by the average mass thousandth fraction of carbon element content, and preceded by T. Such as T9, T12, etc. Purpose: Mainly used for manufacturing various cutting tools, molds, measuring tools, etc.
4. Cast steel: Cast steel number is preceded by ZG. Purpose: Mainly used for manufacturing parts with complex shape and need certain strength, plasticity and toughness, such as gears, couplings, ect.
