BBN S355JR plate, A36, A573 equivalent steel equivalent grades

The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

Cold rolled coil products S355JR plate, A36, A573 equivalent have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products S355JR plate, A36, A573 equivalent is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils S355JR plate, A36, A573 equivalent with different surface roughness can be produced (glossy surface or matte surface, etc.).

Steel transportation because of the special material of S355JR plate, A36, A573 equivalent steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.

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 S355JR plate, A36, A573 equivalent increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of S355JR plate, A36, A573 equivalent during tempering, while tempering determines the performance and life of the workpiece.
