grade 05CuPCrNi distributors near me

ASTM A242 is a kind of high strength low alloy steel with good atmospheric corrosion resistance. Some applications show that it grade 05CUPCRNI has better corrosion resistance than ASTM A36 steel plate and ASTM a572 50 steel plate. Like weathering steel, it can be used without painting, and corrosion naturally stops and becomes a protective layer.

The cold working performance of grade 05CUPCRNI and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of grade 05CUPCRNI and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the grade 05CUPCRNI steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
