One of the mechanical properties of stainless steel or heat resistant steel plate regardless of overall performance austenitic steel has the best of both adequate strength, have excellent hardness plastic while not high, and this is the reason they are widely used . The vast majority of austenitic stainless steel with other materials like metal, its tensile strength, yield strength and hardness, with decreasing temperature; plasticity is reduced as the temperature decreases. The tensile strength increase in the temperature range of 15 ~ 80 ° C is relatively uniform. More importantly: stainless steel screws with decreasing temperature, slowly reducing its impact toughness, Jiyang stainless steel screws, there is no brittle transition temperature. So stainless steel at low temperature to maintain sufficient plasticity and toughness. 316 and 317, which contain alloying elements Mo, Jiyang stainless steel screws ring, so their high-temperature strength and corrosion resistance than 18-8 stainless steel high. 321 and 347, 321 contain a more stable alloy elements Ti, 347 type containing Nb, Jiyang stainless steel screws self-tapping screws, thereby increasing the material's resistance to intergranular corrosion. Not annealed or stainless steel fasteners in 420 ~ 1013 ℃ after serving applies to welding. One of the mechanical properties of stainless steel or heat resistant steel plate regardless of overall performance austenitic steel has the best of both adequate strength, have excellent hardness plastic while not high, and this is the reason they are widely used . The vast majority of austenitic stainless steel with other materials like metal, its tensile strength, yield strength and hardness, Jiyang stainless steel screws cotter pins, along with decreasing temperature; plasticity is reduced as the temperature decreases. The tensile strength increase in the temperature range of 15 ~ 80 ° C is relatively uniform. More importantly: stainless steel screws with decreasing temperature, slowly reducing its impact toughness, there is no brittle transition temperature. So stainless steel at low temperature to maintain sufficient plasticity and toughness.
