ASTM A387 Grade 5 Class 1 material is a Class of chromium-molybdenum alloy steel. Chromium-molybdenum alloy steel, also known as medium-temperature hydrogen-resistant steel, can be deeply quenched. Because of its special high quality performance, it is often used to manufacture some high temperature and high pressure resistant valves and pressure vessels.
ASTM A387 Grade 5 Class 1 steel has the following performance: 1. Good quenching, deep quenching can be carried out, instead of the market anti-saw lock surface quenching 2. Less tendency to temper brittleness 3. Good high temperature processing, beautiful after processing 4. Good welding property 5. The shock absorption performance is good, the hammer will have a rebound feeling, unable to carry out violent destruction
