ASTM A 387 Grade 5 Class 2 Plates are mainly used in equipment that operates under high temperature and pressure. These plates are made from chromium-molybdenum alloy steel and are widely trusted in industries where strength, heat resistance, and reliability are essential.

What Makes ASTM A 387 Grade 5 Class 2 Special

This grade contains chromium and molybdenum, which improve the plate’s strength and its ability to handle heat. The “Class 2” condition means the plates are heat treated, giving them higher tensile strength and better mechanical performance compared to Class 1.

Because of this, these plates are commonly used in pressure vessels and boilers that operate in demanding environments.

Strength and Heat Resistance

ASTM A 387 Grade 5 Class 2 Plates are designed to perform well at elevated temperatures. They maintain good strength and toughness even when exposed to continuous heat. The chromium content helps resist oxidation, while molybdenum improves resistance to softening under high temperatures.

This makes the plates suitable for long-term service without loss of performance.

Good ...
... Resistance to Corrosion

While these plates are not meant for highly corrosive chemical environments, they offer better corrosion resistance than carbon steel. They perform well in environments involving high temperature steam, oil, and gas, where durability and stability are required.

Fabrication and Welding

ASTM A 387 Grade 5 Class 2 Plates can be cut, formed, and welded using standard fabrication methods. Preheating and post-weld heat treatment are usually recommended to maintain strength and avoid cracking. When proper procedures are followed, the plates perform reliably in welded structures.

Standards and Specifications

These plates are manufactured according to ASTM A 387 specifications and are supplied in Class 2 heat-treated condition. They are available in different thicknesses and sizes to meet various industrial requirements.

Common Applications

ASTM A 387 Grade 5 Class 2 Plates are widely used in:

Pressure vessels

Boilers

Heat exchangers

Oil and gas processing equipment

Petrochemical plants

Power generation systems

Why Choose ASTM A 387 Grade 5 Class 2 Plates
