ASTM A387 Grade 5 Class 2 boiler steel, SA387Gr5CL2 for short, is an American standard vessel plate primarily used for welding boilers and high temperature pressure vessels. It is a chromium-molybdenum alloy steel plate, which belongs to high temperature steel, and its chemical composition is equivalent to China's Cr5Mo.
ASTM A387 Grade 5 Class 2 boiler steel Features:
SA387Gr5CL2 steel plate has high strength, high toughness, and good corrosion resistance and oxidation resistance.
The steel plate can maintain stable mechanical properties and chemical stability under high temperature environment.
Steel plate has good processing properties, such as cutting, bending, crimping, etc., and excellent welding performance, can be connected by various welding methods.
In practical application, SA387Gr5CL2 steel plate shows good fatigue resistance and corrosion resistance.
It also has good resistance to water corrosion and seawater corrosion, which is suitable for applications in Marine engineering and other fields.
The delivery status of SA387Gr5CL2 steel plate usually includes the following:
Delivered in annealed, normalized and tempered condition.
When the Purchaser consents, the cooling may also be accelerated from the austenitizing temperature by blowing or liquid cooling, followed by tempering.
According to different needs, we can do normalization, tempering, modulation and other technical delivery.
In addition, the thickness extension of SA387Gr5CL2 steel plate can be 'z15, z25, z35' treatment when necessary, and the steel plate thickness detection comes with three probes and can be '1 probe and 2 probe'.
