In order to open up the market and realize mutual benefit, we will serve our customers wholeheartedly with the business philosophy of "price, quality" and "integrity, service"
Over the years, the company has established a standard of ABS E40 hull structural steel steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to ABS E40 hull structural steel quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than ABS E40 hull structural steel. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel ABS E40 hull structural steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
Manganese steel plate is a kind of common steel, which is a kind of high-strength anti manganese steel. ABS E40 hull structural steel, Manganese steel plate is mainly used to bear the impact, extrusion, material wear and other severe working conditions. It is a typical anti-wear steel, with austenite and carbide as cast structure. After water quenching at about 1000 ° C, the structure changes into single austenite or austenite with a small amount of carbide.
Our company will accept the product quality objection registration record, pass it to the ABS E40 hull structural steel production unit and relevant departments, and timely coordinate the supervision of product ABS E40 hull structural steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
