SA633 Gr E carbon steel plate sheet sheet properties and usage

The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.

The company formulates appropriate SA633 Gr E carbon steel plate sheet product internal control components, strictly controls the fluctuation range of chemical components, and ensures the stability of steel plate performance. Strengthen batching control and smelting operations, effectively control the content of harmful elements such as Sn, Sb, As, Cu, and reduce the content of P and S to improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of steel. It adopts controlled heating to ensure heating time and temperature, and measures such as controlled rolling to ensure the inherent quality of the steel plate.

Best quality of steel raw materials used (A516 Grade 60). Our structural steel plates and sheets are of high quality of work. Moreover, these are also highly repellent to erosion. These plates are also featured by the following properties. Incredible weld-ability of plates. Long-lasting boiler plates. Appropriate durability of the plates SA633 Gr E carbon steel plate sheet. Highly resistant to corrosion. Highly resistant to deterioration and lastly, precise finish.

TMCP process is an indispensable technology for our production of low alloy high strength wide and SA633 Gr E carbon steel plate sheet thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy SA633 Gr E carbon steel plate sheet and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. SA633 Gr E carbon steel plate sheet, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
