Rapid Delivery for Embossed Stainless Steel Sheet - Stainless Steel Round Bar With Good Quality – JINBAICHENG

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.

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.
