In recent years, in line with the development trend of iron and steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Low carbon alloy steel, the total amount of alloy elements is generally ≦3%; the low carbon alloy steel strength is significantly higher than that of carbon steel, with better plasticity and toughness, and weldability is acceptable; low alloy steel includes carbon manganese series, carbon manganese vanadium series, chromium molybdenum series, chromium molybdenum vanadium series. Molybdenum and chromium molybdenum vanadium alloy steels are commonly used as materials for hydrogen corrosion resistance, high temperature sulfur or hydrogen sulfide corrosion resistance and heat resistance (sub high temperature).
A573 Gr 70 plate,09CuPCrNi-A weather-resistant steel plate is one of weather-resistant steel (that is, atmospheric corrosion-resistant steel), used in sulfur-containing flue gas, air preheater, economizer, boiler air preheater, to prevent the vicinity of acid dew point, etc. Commonly used is low temperature weathering steel, which has a strong ability to resist low temperature corrosion. This type of steel has a protective effect against corrosion.
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.
Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.A573 Gr 70 plate
Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
A573 Gr 70 plate,After-sales service team is a key department to test the steel quality Product quality is always the foundation of our survival and development The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest,A573 Gr 70 plate.
