HSLA structural material grade 1.8928 yield strength

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable material grade 1.8928 steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.

Cold rolled coil products material grade 1.8928 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 material grade 1.8928 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 material grade 1.8928 with different surface roughness can be produced (glossy surface or matte surface, etc.).
