高强度钢-双相（DP）钢
High strength steel and dual phase (DP) steel
DP钢板的主要组织是铁素体和马氏体，其中马氏体的含量在5%～20%，强度为500～1200MPa。双相钢具有低屈强比、高的加工硬化指数、高烘烤硬化性能、没有屈服延伸和室温时效等特点。DP钢一般用于需高强度、高的抗碰撞吸收能且也有一定成形要求的汽车零件， 如车轮、 保险杠、 悬挂系统及其加强件等。双相钢的基本成分为C和Mn，有时为了提高淬透性还添加一定量的Cr和Mo。
The main microstructure of DP steel plate is ferrite and martensite, the content of which is 20% ~ 5%, the strength is 500 ~ 1200MPa. The dual phase steel has the characteristics of low yield strength ratio, high work hardening index, high bake hardening property, no yield extension and room temperature aging. DP steel is generally used for the need of high strength, high impact resistance and can also have a certain form of forming requirements of automotive parts, such as wheels, bumper, suspension system and its strengthening parts, etc.. The basic components of the dual phase steel are C and Mn, and sometimes in order to improve the degree of quenching, a certain amount of Cr and Mo are added.
高强度钢-复相（CP）钢

High strength steel and complex phase (CP) steel
CP钢同TRIP钢的组织类似，只是CP钢中含有马氏体而非残余奥氏体。通过马氏体和贝氏体以及析出强化的复合作用，CP钢的强度可达800～1000MPa，特别适合于车门防撞杆、保险杠和B立柱等安全零件。
The CP steel is similar to that of the TRIP steel, but it is a CP steel that contains martensite rather than retained austenite. The strength of CP steel can reach 800 ~ 1000MPa, and is especially suitable for the safety parts of the door bumper, the bumper and the B column, through the combination of martensite and bainite and precipitation strengthening.
高强度钢-马氏体（M）钢
High strength steel and martensite (M) steel
M钢的生产是通过高温的奥氏体组织快速淬火转变为板条马氏体组织，可通过热轧、冷轧连续退火或成型后热处理实现，是目前商业化高强度钢板中强度级别最高的钢种。主要用于成型要求不高的车门防撞杆等零件代替管状零件，减少制造成本。
M steel production is rapidly quenched by high temperature austenite into lath martensite, through hot rolling, cold rolling and continuous annealing or heat treatment after forming, is currently the highest level of commercial steel strength in high strength steel. Mainly used for the molding requirements of the door is not high, such as the replacement of parts of the pipe parts of the pipe parts, reduce manufacturing costs.
高强度钢-MnB钢
High strength steel -MnB steel
MnB钢或热成形钢主要含有Mn和B等元素，具有非常好的淬透性。热成形过程包括将毛坯件加热奥氏体化，然后在红热状态将钢板冲压成形，然后利用模具的冷却能力将零件淬硬成马氏体。整个成形过程约需要15～25s。
MnB steel or hot formed steel mainly contains elements such as Mn and B, which have very good quenching properties. The hot forming process including blank austenitizing, and then steel stamping in the hot heat, then the cooling capacity of mould parts to be hardened into martensite. The whole forming process takes about 15 to 25s.
