Stainless Steel Round Bar With Good Quality
Structural Composition
Iron (Fe): is the basic metal element of stainless steel;
Chromium (Cr): is the main ferrite forming element, chromium combined with oxygen can generate corrosion-resistant Cr2O3 passivation film, is one of the basic elements of stainless steel to maintain corrosion resistance, chromium content increases the passivation film repair ability of steel, the general stainless steel chromium content must be above 12%;
Carbon (C): is a strong austenite forming element, can significantly improve the strength of steel, in addition to carbon on corrosion resistance also has a negative impact;
Nickel (Ni): is the main austenite forming element, can slow down the corrosion of steel and the growth of grains during heating;
Molybdenum (Mo): is the carbide forming element, the carbide formed is extremely stable, can prevent the grain growth of austenite when heated, reduce the superheat sensitivity of steel, in addition, molybdenum can make the passivation film more dense and solid, thus effectively improving the stainless steel Cl- corrosion resistance;
Niobium, titanium (Nb, Ti): is a strong carbide forming elements, can improve the steel's resistance to intergranular corrosion. However, titanium carbide has a negative impact on the surface quality of stainless steel, so the stainless steel with high surface requirements is generally improved by adding niobium to improve performance.
Nitrogen (N): is a strong austenite forming element, can significantly improve the strength of steel. But the aging cracking of stainless steel has a greater impact, so the stainless steel in stamping purposes to strictly control the nitrogen content.
Phosphorus, sulfur (P, S): is a harmful element in stainless steel, the corrosion resistance and stamping of stainless steel can have a negative impact.

Material And Performance
| Material | Characteristics |
| 310S stainless steel | 310S stainless steel is austenitic chromium-nickel stainless steel with good oxidation resistance, corrosion resistance, because of the higher percentage of chromium and nickel, 310S has much better creep strength, can continue to work at high temperatures, with good high temperature resistance. |
| 316L stainless steel round bar | 1) Good glossy and beautiful appearance of cold rolled products.
2) excellent corrosion resistance, especially pitting resistance, due to the addition of Mo 3) excellent high temperature strength; 4) excellent work hardening (weak magnetic properties after processing) 5) non-magnetic in solid solution state. |
| 316 stainless steel round steel | Characteristics: 316 stainless steel is the second most widely used steel after 304, mainly used in the food industry and surgical equipment, because of the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used in harsh conditions; excellent work hardening (non-magnetic). |
| 321 stainless steel round steel | Characteristics: The addition of Ti elements to 304 steel to prevent grain boundary corrosion, suitable for use at temperatures of 430 ℃ - 900 ℃. Other than the addition of titanium elements to reduce the risk of material weld corrosion other properties similar to 304 |
| 304L stainless round steel | 304L stainless round steel is a variant of 304 stainless steel with a lower carbon content and is used in applications where welding is required. The lower carbon content minimizes the precipitation of carbide in the heat affected zone close to the weld, which can lead to intergranular corrosion (weld erosion) of stainless steel in certain environments. |
| 304 stainless steel round steel | Characteristics: 304 stainless steel is one of the most widely used chromium-nickel stainless steel, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. Corrosion resistance in the atmosphere, if the industrial atmosphere or heavy pollution areas, it needs to be cleaned in time to avoid corrosion |
Typical Use
Stainless steel round steel has a broad application prospect and is widely used in hardware and kitchenware, shipbuilding, petrochemical, machinery, medicine, food, electric power, energy, aerospace, etc., construction and decoration. Equipment for use in sea water, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal area facilities, ropes, CD rods, bolts, nuts
Main Products
Stainless steel round bars can be divided into hot rolled, forged and cold drawn according to the production process. Hot-rolled stainless steel round steel specifications for 5.5-250 mm. Among them: 5.5-25 mm of small stainless steel round steel mostly supplied in bundles of straight bars, commonly used as steel bars, bolts and various mechanical parts; stainless steel round steel greater than 25 mm, mainly used in the manufacture of mechanical parts or for seamless steel billets.
