hot rolled 09CuPCrNi-B steel equivalent inventory 2021

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 09CUPCRNI-B steel equivalent 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 09CUPCRNI-B steel equivalent etc. steel is strictly controlled.

We do sand blasting and shop primer for various 09CUPCRNI-B steel equivalent steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer 09CUPCRNI-B steel equivalent thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.

Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel 09CUPCRNI-B steel equivalent can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.

we are the best professional steel manufacturer in China. We can supply kinds of steel product size，if you want to purchase steel plate or steel pipe and other products. Please contact us freely. we can give you the 09CUPCRNI-B steel equivalent best price with high quality.
