It has a remarkable effect on the mechanical properties of the metal. The temperature, the alloying elements and the thermal impregnation time affect the grain size. As a general rule, a small grain size is better as it has higher tensile strength, higher hardness and is less deformed during quenching, being less vulnerable to cracking.. The grain size is determined microscopically by counting AUSA special steels The influence of the components on The grain of the steels is specified from number 1 for the coarsest grain to 8 for the finest. A good steel must have a grain size of 6 or above. It is an alloy element in nitrided steels. Sulphur (S):this is normally an impurity and is kept at a low level.

Hot stamping is a well-known process to produce structural automotive parts with an excellent strength-to-weight ratio. However, this process is more expensive due to the lower energy efficiency and operating cost of the traditional roller-hearth furnace. Additionally, lower ductility and toughness are commonly recognized as the main disadvantages of the current hot stamped ultra-high-strength Novel 1.5 GPa-strength with 50%-ductility by Apr 28, 2017 · In austenite grains of the non-recrystallized region, 27MnCrB5) composed of full martensite matrix used for structural reinforcement components, the yield and tensile strengths are very high above 1.0 and 1.5 GPa, respectively, whereas their elongation is low below 8% 4.
