304 304L2mm 4mm 2b ASTM AISI ss 201 202 304 304L 316 316L 321 Laminas de acero inoxidable stainless steel sheet plate

304 stainless steel: 0Cr18Ni9 (0Cr19Ni9) 06Cr19Ni9 S30408

Chemical composition :C: ≤0.08, Si: ≤1.0 Mn: ≤2.0, Cr: 18.0 ~ 20.0, Ni: 8.0 ~ 10.5, S: ≤0.03, P: ≤ 0.035N ≤0.1.

With 304L
304L is more corrosion resistant, 304L contains less carbon.

304 is widely used, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping bending and other good thermal processing, no heat treatment hardening phenomenon (no magnetic, using temperature -196°C~800°C).

304L has excellent resistance to grain boundary corrosion after welding or stress elimination. In the case of no heat treatment, can also maintain good corrosion resistance, using temperature of -196°C-800°C.

According to the microstructure characteristics of steel grades, it can be divided into 5 types: austenite type, austenite-ferrite type, ferrite type, Martensite type and precipitate hardening type. Requirements can withstand oxalic acid, sulfuric acid-ferric sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acid and other acids corrosion, widely used in chemical industry, food, medicine, paper making, petroleum, atomic energy and other industries, as well as construction, kitchenware, tableware, vehicles, household appliances and various parts.

Stainless steel plate surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is an alloy steel that is resistant to rust, but not absolutely resistant to rust.

Stainless steel plate according to the method of hot rolling and cold rolling of two, including thickness of 0.02-4 mm thin cold plate and 4.5-100 mm thick plate.

In order to ensure that all kinds of stainless steel plate yield strength, tensile strength, elongation and hardness and other mechanical properties meet the requirements, steel plate before delivery must undergo annealing, solution treatment, aging treatment and other heat treatment

The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal organizational structure, the main role is chromium element. Chromium has high chemical stability, forming a passivation film on the surface of the steel, isolating the metal from the outside world, protecting the steel from oxidation and increasing the corrosion resistance of the steel. The corrosion resistance of the passivation film decreases when it is damaged.

Jiangsu Irunt Steel Group Co., Ltd. is located in Wuxi City , Jiangsu Province, China, which is the largest steel production base. After 30 years of efforts, it has grown from a family factory to a group company.

The group company mainly produces and sells a series of steel products such as steel pipe, steel coil, steel plate, copper pipe, copper plate, copper strip, aluminum pipe, aluminum plate, galvanized steel pipe, galvanized coil, galvanized plate and so on.The group company has established five platforms, including three production plants and two processing plants. At present, it is still expanding its production line, basically forming a development model of integration of production, processing and sales.

Our annual production capacity of various specifications is about 1 million metric tons. In addition to being a supplier of our series of products, the group company is also committed to expanding its commitment to customers by strengthening services and adding new facilities. A dedicated team is responsible for providing technical support, recommending the correct use of steel, and assisting customers to give full play to their products.

Over the years, we have opened up new markets in Africa, Southeast Asia, the Middle East and America. Our best service and excellent quality have led long-term partners in many countries and established continuous business relations with all customers. Our principle is "service first, sales second". Most of the time, we have comprehensive inspection and procurement to control the quality of finished products. We will have a professional inspection team to test each delivery of products.

Since its establishment, in line with the mission of "contributing high-quality products and services to the world" and the core values of "customer first, excellence, coexistence and win-win", we ensure that we can deeply cooperate with all our friends in the field of iron and steel, and win more affirmation and praise from the market and customers with its high-quality products, perfect product team and thoughtful service, I believe tomorrow will be better!
