Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, CCS grade A ferries steel and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.
A633Gr.C,D steel plate A537CL1/A633Gr.C,D steel plate, under ASTM-SAE standard A537CL1/A633Gr.C,D steel plate, under ASTM-SAE standard, we can regard CCS grade A ferries steel, A537CL1/A633Gr.C,D steel plate as Fine-grain structural steels, normalised rolled steel. A537CL1 steel plate is one mainly of Fine-grain structural steels, normalised rolled steel,A537CL1/A633Gr.C,D steel plate is under ASTM-SAE standard equivalent to DIN:TStE355, EN:S355NL, which with a minimum impact energy of 20J at temperatures not lower than -20 degree and the tensile strength of A537CL1/A633Gr.C,D is 4800 to 620 MPa.
CCS grade A ferries steel, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This CCS grade A ferries steel alloy steel CCS grade A ferries steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
Our quality and service commitment: CCS grade A ferries steel product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
Analyze the advantages and disadvantages of the products against the competitive CCS grade A ferries steel products. Understand the industry situation and future trend. Understand the product brand positioning appeal point, focus on the crowd and development direction. Understand the layout of each market area, and form a big strategic layout view.
