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 BV DH32 oil tanker steel 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 BV DH32 oil tanker steel long-term cooperation with you.
As the thickness and hardness of BV DH32 oil tanker steel increase, the tendency to crack at the cutting edge increases. In order to prevent the BV DH32 oil tanker steel from cutting cracks, preheating should be carried out before BV DH32 oil tanker steel cutting. Special attention should be paid to preheating to make the entire BV DH32 oil tanker steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole BV DH32 oil tanker steel cannot be preheated, the partial preheating method can be used instead.
Weathering steel plates have an excellent corrosive resisting property like resistance to crevice and pitting corrosion, resistance to corrosion and oxidation. This plate also has resistance to chloride corrosion cracking and stress corrosion. These plate are not affected very easily by acids and environmental rust and works in the sulfide atmosphere. BV DH32 oil tanker steel, Weather resistant steel plates have excellent workability, formability, easy to install, easy to fabricated, machinability, durability, reliability.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, BV DH32 oil tanker steel sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
