Heat treatment for stainless steel

 Types of Steel Products The molten steel produced in the steelmaking furnace is cast into bil, ingots, or blooms, which are then processed under pressure to form steel products. There are many types of steel products, which can generally be divided into major categories: sections, plates, tubes, and wires. 1. Sections There are many types of sections, which are solid, long steel products with certain cross shapes and sizes. They can be further divided into simple and complex sections based on their cross-sectional shapes. The former includes round steel, square steel, flat, hexagonal steel, and angle steel; the latter includes rails, I-beams, channel steel, window frame steel, and special-shaped steel, etc. Small steel with a diameter of 6.5-9.0mm is called wire. 2. Plates Plates are flat steel products with a large width-thickness ratio and surface area. They are divided into thin plates (thickness <4mm), medium plates (thickness 4-25mm), and thick (thickness >25mm) based on their thickness. Steel strips are also included in the category of plates. 3. Tubes Tubes are long steel with a hollow cross-section. They can be divided into round tubes, square tubes, hexagonal tubes, and various special-shaped section tubes based on their cross-sectional. They can also be divided into seamless steel tubes and welded steel tubes based on their processing methods. 4. Wires Wires are the result of further processing of wire. They can be divided into round wires, flat wires, and triangular wires based on their shapes. Wires are not only used directly but also producing wire ropes, wire strands, and other products. According to their shapes, they can be divided into wire, sections, plates, tubes, and metal products Wire: common wire, high-quality wire, rebar Sections: I-beam, channel steel, angle steel, square steel, heavy rail, high steel, special-shaped steel, round steel, unequal-angle steel, flat steel, light rail, gear steel, hexagonal steel, heat-resistant steel, alloy steel carbon steel, stainless steel, bearing steel,
