The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing A633Gr.D physical properties high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.
Structural steel for construction is used to build boilers, ships, bridges, workshops and other building materials. This kind of steel usually needs welding construction, so it is generally low carbon steel with carbon content less than 0.25%, which is mostly used in hot rolling or normalizing state. A633Gr.D physical properties, Structural steel for machinery is used for manufacturing machines or mechanical parts. This kind of steel is often used after carburizing or quenching and tempering. The steel used for carburizing is low carbon steel with carbon content of 0.1% ~ 0.3%. Steel used for quenching and tempering refers to medium carbon steel with carbon content of 0.3% ~ 0.6%.
Different form A633Gr.D physical properties, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.
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. A633Gr.D physical properties, 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.
Chemical composition of A633Gr.D physical properties, 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.
