Regardless of the stainless steel plate or heat resistant steel plate, the comprehensive performance of austenitic steel is best, not only has enough strength, and has excellent plasticity and hardness is not high, it is also one of the reasons they are widely used. Austenitic stainless steels are similar to most other metal materials, and their tensile strength, yield strength and hardness increase with decreasing temperature, while plasticity decreases with decreasing temperature. Its tensile strength increases at a temperature range of 15~80 degrees C, which is even. 

More importantly, as the temperature decreases, the impact toughness decreases slowly, and there is no brittle transition temperature. Therefore, stainless steel can maintain sufficient plasticity and toughness at low temperatures. E-BON the most excellent stainless steel company, which provide you with Professional Black Boston Cocktail Shaker.

Stainless steel pipe, stainless steel heat resistance, heat resistance, refers to the high temperature, both antioxidant or gas medium corrosion resistance, namely thermal stability, while in high temperature double enough strength, namely heat intensity. E-BON the stainless steel specialist, China Stainless steel Barware factory.
The influence of carbon carbon in austenitic stainless steel is strong and the expansion of the formation and stabilization of austenite austenite element. Carbon austenitic formation capacity is about 30 times that of nickel, carbon is a gap element, by solution strengthening can significantly improve the strength of austenitic stainless steel. Carbon can also improve the austenitic stainless steel in high concentration chloride (such as 42%MgCl2 in boiling solution) resistant to stress corrosion performance, but in austenitic stainless steel, carbon is often regarded as a harmful element, this is mainly due to some conditions in the use of stainless steel and corrosion (such as welding or by heating, the temperature of 450~850 DEG C) carbon can form Cr23C6 carbon high chromium compounds steel and chromium in causing local chromium depletion and corrosion resistance of the steel is intergranular corrosion resistance decreased. 

Therefore, Ni Cr austenitic stainless steel in 60s since the new development is mostly carbon content In 0.03% or 0.02% ultra low carbon, can know with a decrease in the carbon content of steel intergranular corrosion sensitivity decreased, when the carbon content is lower than 0.02% has the most obvious effect, some experimental Pearl also pointed out that the point corrosion of carbon chromium austenitic stainless steel will increase the tendency. 

Due to the deleterious effect of carbon, carbon control the content of as low as required not only in austenitic stainless steel and smelting, but also in the subsequent heat, to prevent the stainless steel surface carburizing in cold working and heat treatment process, carbide and free of chromium.
