Big mill hot rolled BP600 bulletproof steel grade

The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing BP600 bulletproof steel grade high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.

BBN company is one of the most important manufacturers of BP600 bulletproof steel grade medium and heavy steel plates for shipbuilding in China. The general strength shipbuilding steel Grades A, B, D, E and higher-strength grade AH32, AH36, DH32, DH36, EH32, EH36 hull structural steel plates produced by heavy steel (specifications: 6-32mm) have been obtained by nine classification society approval certificates Like ABS, CCS, LR, DNV, GL, RINA, and KR.

BP600 bulletproof steel grade, 09CrCuSb steel has the following advantages: 1. The alloy ratio is optimized and rare alloy is added. The finished steel product has excellent sulfuric acid uniform corrosion resistance. 2. The content of As, Sn, Pb and other elements, and the gas content of hydrogen, oxygen and nitrogen are controlled to improve the purity of the billet. According to the analysis of many times, the grain size of the material is not coarser than grade 6. The corrosion resistance of the equipment made of 09CrCuSb steel is improved, and the maintenance cycle is relatively prolonged, which has great economic benefits.

As the thickness and hardness of BP600 bulletproof steel grade increase, the tendency to crack at the cutting edge increases. In order to prevent the BP600 bulletproof steel grade from cutting cracks, preheating should be carried out before BP600 bulletproof steel grade cutting. Special attention should be paid to preheating to make the entire BP600 bulletproof steel grade interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole BP600 bulletproof steel grade cannot be preheated, the partial preheating method can be used instead.

SA537 grade 70 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the BP600 bulletproof steel grade, SA537 grade 70 steel coil thickness should not exceed 25 mm. The mechanical properties of SA537 grade 70 steel is yield strength is 290MPa, and the tensile strength is 485-620Mpa.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality BP600 bulletproof steel grade products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
