310 Stainless Steel Mechanical Properties: Tensile Strength, Hardness & Toughness

1. What is the tensile strength and yield strength of 310 stainless steel at room temperature? Answer: Tensile strength ≥515MPa, yield strength ≥205MPa, which has good load-bearing capacity.

2. How does the hardness of 310 stainless steel change with heat treatment? Answer: The hardness is relatively low after solution annealing, and can be appropriately increased by cold working, but it will decrease after high-temperature use.

3. What is the toughness of 310 stainless steel at low temperatures? Answer: It has good toughness at low temperatures, no brittle transition, and can be used in low-temperature environments.

4. How does the mechanical strength of 310 stainless steel change at high temperatures? Answer: The strength will decrease with the increase of temperature, but compared with other stainless steels, it still maintains higher strength at high temperatures.

5. What is the fatigue strength of 310 stainless steel? Answer: It has good fatigue strength, which can withstand repeated loads, making it suitable for components subject to cyclic stress.
