Our team has been engaged in export business for more than ten years and has rich experience in steel, which can provide customers with professional advice in the application of different materials. We mainly supply stainless steel, carbon steel, galvanized, aluminum, copper series and other products. In addition, we can customize products according to customers' requirements. Comply with GB standard, ASTM standard, JIS standard, EN and other standards. We also welcome OEM and ODM orders.

High carbon steel, often called tool steel, contains from 0.60% to 1.70% carbon and can be hardened and tempered. Hammers, crowbars, etc. are made of steel with a carbon content of 0.75%; cutting tools such as drills, taps, reamers, etc. are made of steel with a carbon content of 0.90% to 1.00%.
Generally, high carbon steel has high strength and is widely used in cutting, drilling, lathe, milling and other environments that require high hardness. Medium carbon steel Carbon steel with a carbon content of 0.25% to 0.60%. There are killed steel, semi-killed steel, boiling steel and other products. In addition to carbon, it can also contain a small amount of manganese (0.70% to 1.20%).
According to product quality, it is divided into ordinary carbon structural steel and high-quality carbon structural steel. Good thermal processing and cutting performance, poor welding performance. The strength and hardness are higher than those of low carbon steel, while the plasticity and toughness are lower than those of low carbon steel. Hot-rolled and cold-drawn materials can be used directly without heat treatment, or they can be used after heat treatment. The quenched and tempered medium carbon steel has good comprehensive mechanical properties. The highest hardness that can be achieved is about HRC55 (HB538), and σb is 600-1100MPa. Therefore, among various uses of medium strength level, medium carbon steel is the most widely used, in addition to being used as a building material, it is also widely used in the manufacture of various mechanical parts. Mild steel, also known as mild steel, carbon content from 0.10% to 0.30% low carbon steel is easy to accept various processing such as forging, welding and cutting, commonly used in the manufacture of chains, rivets, bolts, shafts, etc.

Galvanized sheet is a layer of metal zinc on the iron sheet for anti-corrosion. There are cold galvanizing and hot galvanizing. In short, the zinc on the surface will fall off for a long time, and the iron will be corroded. Stainless steel does not need anti-corrosion. Of course, the price is expensive. Stainless steel is 200-300 degrees, only some special materials are tempered at 200-300 degrees low temperature, but the temperature is too low, there is generally not much change, and the zinc on the lower layer of the galvanized sheet will be slowly removed at high temperatures (200 degrees, 300 degrees). Bake off.
There are many types of stainless steel, and the galvanized sheet is only plated with metallic zinc on the surface of the steel sheet or iron sheet. The galvanized sheet itself is a common sheet, and it is only surface processed. The stainless steel plate is an acid-resistant alloy plate of Fangfu. Depending on what you do, 200-300 degrees is not considered a high temperature, and the price of relatively cheap stainless steel 430 plate should be twice as expensive as that of galvanized plate of the same specification.
Stainless steel achieves the purpose of changing the composition of the steel by adding trace elements to achieve the anti-corrosion function. Galvanized sheet is galvanized on the surface of ordinary steel plate to achieve anti-corrosion purpose by sacrificing zinc. 200 degrees and 300 degrees are not a problem for metals. Depending on the environment, there will be some extremely small effects, but it will take a long time for changes.
