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 Q355GNH Z35 plate 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 Q355GNH Z35 plate to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
If the wall thickness of the elbow is relatively thick, it is best to perform stress relief heat treatment on the weldment immediately after welding. This is especially true for large-thickness weldments Q235B, high-rigidity structural parts, and weldments that work under severe conditions (dynamic load or impact load). The tempering temperature for stress relief is 600~650℃. For thin-walled elbows, stress heat treatment is not necessary after welding.
Strip steel is coiled and curved steel plate, which is different from common steel pipes and steel plates. Strip steel has obvious characteristics. First, it is thin and easy to curl, which is convenient for logistics and transportation. Second, the surface quality of Q355GNH Z35 plate, strip steel is good, the luster is bright and it has good flexibility. Third, the strip steel is easy to process. When you need to use it, you only need to straighten the bent part and you can directly process it. Fourth, the precision is high, and the strip steel can be made of plain carbon steel, carbon structure steel, spring steel, tool steel, stainless steel, etc.
Alloying elements can strengthen the properties of structural steels. Q355GNH Z35 plate, Alloy structural steel has suitable hardenability. After proper metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite. Therefore, alloy structural steel has higher tensile strength and yield ratio (generally about 0.85), higher toughness and fatigue strength, and lower ductile brittle transition temperature. Alloy structural steel can be used to manufacture machine parts with larger section size.
As to the Chemical composition, the different content is a main on carbon content, while the carbon content of Q355GNH Z35 plate, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).
We have our own factory, including the production and manufacturing of steel pipes, with a special Q355GNH Z35 plate steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect Q355GNH Z35 plate after-sale service guarantee system, lets the customer save the worry and the labor.
