41Cr4 (1.7035) material is an alloy structural steel grade commonly used internationally. Its tensile strength, yield strength and hardenability are all higher than that of 40# steel, but it also has certain defects that its weldability is limited and there is a tendency to form cracks. 41Cr4 steel is generally used for more important quenched and tempered parts, such as parts that work under alternating loads, medium speed and medium load parts.
We are world class steel materials supplier. We are engaed in providing raw steel materials such as ABS grade D hot rolled strips steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build ABS grade D hot rolled strips long-term cooperation with you.
At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick ABS grade D hot rolled strips steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.
With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of ABS grade D hot rolled strips etc. steel material.
We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
