Hot rolled mild steel strength steel S690Q 2.5 mm thick

According to different strength levels, the ASTM A516 plates are available in four grades: Grades 55, 60, 65, and 70. The most common is Grade 70 or called out A516-70. The maximum thickness of {keyword plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. The mechanical properties such as tensile strength, yield strength, and elongation shall be determined by a tension test for the plates.

Advantages of strength steel S690Q, stainless steel: 1. Chemical properties: the chemical and electrochemical corrosion resistance of stainless steel is the best in steel, second only to titanium alloy. 2. Physical properties: stainless steel has good heat resistance, high temperature resistance, low temperature resistance and even ultra-low temperature resistance. Stainless steel can work safely at - 270℃ - 400℃ for a long time. No matter at high or low temperature, no harmful substances will be precipitated, and the stainless steel material properties are quite stable.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. strength steel S690Q Heat treatment process refers to the ability to change the microstructure and properties of strength steel S690Q after heat treatment, including hardenability, hardenability, temper brittleness, etc.
