09cuptire-a corten steel material grade comparison

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched 09CUPTIRE-A corten steel increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of 09CUPTIRE-A corten steel during tempering, while tempering determines the performance and life of the workpiece.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of 09CUPTIRE-A corten steel etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in 09CUPTIRE-A corten steel etc. steel is strictly controlled.

ASTM Corten B steel is a hot-rolled structural steel product with better atmospheric corrosion resistance under Technical delivery conditions. ASTM Corten B steel conforms to ASTM standard, with yield strength of 355MPa and 345mpa, and the 09CUPTIRE-A corten steel yield strength depends on the thickness. The tensile strength of ASTM Corten B steel is 470-630 MPa.
