With the development of multimodal transport in the international shipping market and the increase of the complexity of the integrated transport chain, modern ports, as the intersection of the three transportation modes of sea, land and air, are developing from traditional transfer and product distribution functions to all-round value-added services, becoming the central link connecting the world's production, exchange, distribution and consumption, and supporting the world economy and international trade An important part of the developed international circulation system.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the A633 Grade A thickness metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between A633 Grade A thickness strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

In January 2019, one of our Vietnam customer purchased 395.62 tonsQ345B steel plateA633 Grade A thickness for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 A633 Grade A thickness and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.

Chemical elements of 42SiMn steel: C: 0.39-0.45, Si: 1.10-1.40, Mn: 1.10-1.40. Mechanical properties of 42SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 40; impact energy: 47J. 42SiMn steel belongs to alloy quenched and tempered steel with good properties, high strength, wear resistance and hardenability. Under certain conditions, the strength, wear resistance and hot working performance of 42SiMn steel are better than 40Cr steel, A633 Grade A thickness, and can be used instead of 40CrNi steel.

Product concept: take the technology leading as the pillar of the enterprise, achieve the development goal of the enterprise with the reliable products, the reliable technology and the trustworthy services, and devote to the creative reform activities leading in the technical development and career of the industry to create new value through continuous change.
