With the development of China's p235gh steel equivalent market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of p235gh steel equivalent products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

S355J2 steel plate p235gh steel equivalent rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the p235gh steel equivalent single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.

The p235gh steel equivalent, wear resistant steel plate is composed of low carbon steel plate and alloy wear-resistant layer, and the alloy wear-resistant layer is 1/3 ~ 1/2 of the total thickness. The alloy wear-resistant layer and the base plate are metallurgically bonded. When working, the base plate provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.

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 p235gh steel equivalent 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.
