Welcome to BBN High Strength Steels Factory
Our company was founded in 2000, which initially committed to providing high-quality steel S460QL equivalent products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export S460QL equivalent steel to the international market, opening up the international steel market.
Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the S460QL equivalent steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its S460QL equivalent steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
"Mirror" refers to the surface state of S460QL equivalent stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.
In 2014, we offered 175 ton Cold rolled stainless steel plate to Thailand. The S460QL equivalent products are from TISCO. Here is the MTC that we offered to customer. We have our own quality team. Our quality team will inspect every order before shipment for customer. Normally, we will test the chemical composition, thickness, width, and length. Here are some pictures for last inspection.
What is the difference between Q345B steel and Q345A steel? S460QL equivalent, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
Product concept: take the technology leading as the pillar of the enterprise, achieve the development goal of the enterprise with the reliable products, the reliable technology and the trustworthy services, and devote to the creative reform activities leading in the technical development and career of the industry to create new value through continuous change.
