In the year of 2015, customer from Peru oil refinery contact with us from Internet. After one month's negotiation and quotation, they chose us as there supplier of raw steel plate steel plate ASTM A572 gr.50 grade ASTM A36. We get an trail order of 300 tons in April. When the first ship arrived, they inspect the steel plate and very happy with the quality we supply. Then they put another 1700 tons order, we sent to them within 90 days. Our company management group visit the customer in the beginning of 2016 and the visit is very successful.
Fine cutting of parts, when the steel plate ASTM A572 gr.50 thickness of parts is not greater than 8mm, the verticality of the section can not be greater than 6% of the thickness of parts;When the thickness of the part is 8-14mm, the verticality of the section should not be greater than 8% of the steel plate ASTM A572 gr.50 thickness of the part.
The company's logistics and transportation department is responsible for developing high-quality third-party logistics companies, to coordinate and follow up the situation of steel materials transportation. Third-party logistics companies provide us with professional logistics services. With this logistics management method, the time for delivery of steel materials is faster, and the logistics service is professional, multifunctional and comprehensive.
The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in steel plate ASTM A572 gr.50 etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.
