SA285GrC A387GR11CL2

introduction

A387GR11CL2 is a low alloy carbon steel plate commonly used in the manufacture of boilers and pressure vessels. It complies with ASTM A285 standards and is primarily used in industrial environments subject to low to medium pressures.

Advantages

1.Good oxidation resistance
SA285GrC A387GR11CL2 contains elements such as chromium and molybdenum. Chromium reacts with oxygen to form a dense chromium oxide film, which can effectively prevent oxygen from further penetrating the steel surface and reduce the occurrence of oxidative corrosion. Molybdenum is a strengthening alloy element. Molybdenum enhances the thermal stability of steel through solid solution strengthening, especially in environments containing corrosive gases such as sulfur and chlorine. The addition of molybdenum can effectively prevent the occurrence of corrosion.

2. Good mechanical properties
The tensile strength of this steel ranges from 380-515 MPa, showing a high load-bearing capacity, suitable for equipment that withstands large tension and pressure; the yield strength is 205 MPa, which can ensure stability and safety under high load conditions; the steel has a minimum elongation of 25%, and can withstand certain deformation when subjected to force without breaking easily.

3.Low temperature toughness
A387GR11CL2 also has good low temperature toughness at low temperatures such as -20℃, 40℃ and -60℃, which is very important for applications in low temperature environments (such as boilers, pressure vessels and other equipment in cold areas).

4.Good processing performance
The phosphorus and sulfur content of this steel is less than 0.035%. Phosphorus and sulfur are impurity elements in steel. When the content is too high, it will increase the brittleness of the steel. Low sulfur and low phosphorus steel can reduce the generation of cracks during welding and ensure the strength and toughness of the welded joint, especially under high or low temperature conditions.

Applications
