Hot rolled Q460E carbon steel plate sheet vs stainless steel

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and Q460E carbon steel plate sheet heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported Q460E carbon steel plate sheet to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

The wear resistant steel plate Q460E carbon steel plate sheet has good processing performance and can be processed into different sizes according to the requirements. Wear resistant steel plate can be cold bent, welded, bent, etc.. The application of wear resistant steel plate Q460E carbon steel plate sheet involves wear-resistant parts of equipment in underground mine, cement industry, road building industry, mining stone, open pit mine and metallurgy industry, etc..

Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ～ 0.75, Mn: 0.20 ～ 0.50, P: 0.07 ～ 0.15, S≤0.03, Cu: 0.25 ～ 0.55 , Cr: 0.30 ～ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet Q460E carbon steel plate sheet is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized Q460E carbon steel plate sheet are higher than that of annealed Q460E carbon steel plate sheet, but the elimination of internal stress is not as good as annealing. The normalizing operation of Q460E carbon steel plate sheet is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Chemical composition of Q460E carbon steel plate sheet, Q345D steel plate: C: ≤0.18; Si: ≤0.50; Mn: ≤1.70; P: ≤0.030; S: ≤0.025; Nb: ≤0.07; V: ≤0.15; Ti: ≤0.20; Cr: ≤0.30; Ni: ≤0.50; Cu: ≤0.30; N: ≤0.012; Mo: ≤0.10; Als: ≥0.015. Yield strength (MPa) of Q345D steel plate: ≤16mm: ≥345; 16-40mm: ≥335; 40-63mm: ≥325; 63-80mm: ≥315; 80-100mm: ≥305; 100-150mm: ≥285; 150-200mm: ≥275; 200-250: ≥275; 250-400: ≥265. Tensile strength of Q345D low alloy steel: 450-630(MPa). Elongation: ≥21. Impact test: -20 ℃: ≥34.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
