304 contains chromium (%) 18 - 20 .304 is equivalent to China's 0Cr19Ni9 (0Cr18Ni9) stainless steel, 304 stainless steel is a general-purpose stainless steel materials, rust resistance than the 200 series of stainless steel materials to be stronger. High temperature resistance is also better than the high to 1000-1200 degrees. 304 stainless steel has excellent stainless corrosion resistance and good resistance to intergranular corrosion properties. In the experiment, it is concluded that: 304 stainless steel material concentration ≤ 65% of the boiling temperature below the nitric acid, has a strong resistance to corrosion. To alkali solutions and most organic and inorganic acids also have good corrosion resistance.

304 (18Cr-8Ni) material: as a widely used steel, has good corrosion resistance / heat resistance, low temperature strength and mechanical properties; stamping / bending and other hot workability, no heat treatment hardening phenomenon (non-magnetic, easy to use temperature cadmium -196 ℃ ~ 800 ℃). Uses: Household goods (1/2 class tableware/cabinet/indoor piping/water heater/boiler/tub), auto parts (windshield wipers/muffler/molded products), medical appliances, building materials, chemical, food industry, agriculture, ship parts.

Grades of stainless steel:

  300 stainless steel series: 301/302/302HQ/303/304/304L/304F/304HC/316/316L/316F/316S/316Ti/310/310S/314/314L/317/317L/321(chromium/nickel-austenitic stainless steel)

  Note: L stands for low carbon, such as 304L has lower carbon content than 304. H and S stand for high temperature resistance, such as 310S is more resistant to high temperature than 310, 304H is more heat resistant than 304.

  Stainless steel bar is divided into round bar, hexagonal bar, square bar, flat bar, round bar and solid bar. Bright surface than the black surface of the expensive, which 303 is a unique material in the bar, belongs to the easy to turn (cut) type material, mainly used for automatic lathe cutting. Another: 304F/303CU/316F are also easy to cut type materials. Specifications: Ф1mm ~ Ф280mm.

Stainless steel theoretical weight calculation formula:

  Weight (kg) = diameter (mm) * diameter (mm) * length (m) * 0.00623

  Stainless steel specific gravity.

  ●Chromium stainless steel is taken as 7.75 tons/M3

  ●Chromium-nickel stainless steel is 7.93 tons/M3

  ●Fe is 7.87 tons/M3

Product Information

We have a full line of stainless steel plate, bar, sheet, tubing, and various other shapes. We have the capabilities to laser cut, shear, and fabricate stainless steel according to yur exact specifications. Our stainless steel is available either cut to size or at full length. Our team of metal experts are available to assist with any custom project.

Round Bar

Stainless steel round bars are categorized as both long products and bar materials. SS round bar is long stainless steel product with its cross section shaping round. The customized length of stainless round bar is 5.8m,6m,4m and the like. Bright stainless steel round bar is cold drawn bar with its finish bright and smooth. Black bar stainless steel is hot rolled SS bar with black surface, or oxide skin produced after exposure to high temperature. Stainless steel round bars (also titled stainless steel rods) are extensively used in fields such as kitchenware, shipbuilding, petrochemicals, equipment, medicine, food, electricity, energy, aerospace, construction and decoration, equipment under seawater, chemistry, dye, papermaking, oxalate, fertilizer production equipment, photography, coastland facilities, wire ropes, CD rod, screws and nuts.

Flat and Square Bar

Stainless steel flat bars are of rectangle shape with root face(or round edges) and they can be semi-finished or finished products in light of applications. In terms of processing technology, there are cold drawn stainless steel flat bars and hot rolled stainless steel flat bars. In terms of surface treatment, SS flat bars have polished finish and sand blast finish. In case of order, dimension, finish, quantity and other technical requirements such as annealing, solution treatment should be clearly stated. Stainless steel flat bars are widely employed in building structures and engineering structures like house beams, bridges, power transmission tower, hoisting and conveying machinery, shipyards, industrial furnace, reaction tower, containers and warehouse shelves, fences, power transmission ships, vehicles etc.

Hexagon Bar

Stainless steel hex bar is solid stainless steel long product with its cross section as hexagonal. We produce stainless hex bars in multiple sizes and various grades. The most commonly applied specification is ASTM A276, which includes both hot-finished and cold-finished bars. Due to its good features such as 1) high precision (tolerance can be ±0.01mm at minimum), 2) bright and smooth finish,3)corrosion resistance, high tensile strength and anti-fatigue strength, stainless steel hex bars are widely used for producing machined components such as hex bolts, hex nuts and hex plugs. In addition, SS hex bars are used for auto parts, elevators, kitchenware, pressure vessels and other promising industries for they are environment friendly and for their long service life.

Plate and Sheet

Stainless steel sheet & SS plate provide a low maintenance, corrosion resistance solution for a variety of industrial applications. Some of the typical uses for stainless steel include:Food Processing & Handling, Storage Tanks, Heat Exchangers, Electrical Enclosures,Chemical Process Vessels, Conveyors,Architectural & Construction, Marine Parts & Equipment
