304 316 cylinder steel rod can not be strengthened by heat treatment like Q+T or induction hardened , but it can be strengthened by cold working deformation (cold work hardening, deformation strengthening), which will increase the strength and decrease the plasticity.
Austenitic SS 304 steel rod has always played the most important role in stainless steel, and its production and usage account for about 70% of the total production and usage of stainless steel cylinder rod. Due to the excellent performance and characteristics of austenitic stainless steel, it has received more and more attention and application. Especially in the manufacturing and production of nuclear power equipment, it is used to manufacture important and critical parts like cylinder barrels or hydraulic presses.
The most basic alloying elements of austenitic stainless steel are chromium and nickel-chromed. The representative grade is chromium-nickel austenitic stainless steel with a chromium content of about 18% and a nickel content of about 8%. The element ratio of chromium and nickel basically ensures that the structure of the steel is stable austenite. Austenitic stainless steel is developing rapidly. In order to adapt to the needs of different conditions, other alloying elements are added to 18-8 steel to give this type of stainless steel better properties.
