Grade 304 Stainless Steel Coils/Strips

First, the yield strength of cold-rolled stainless steel strips are better than hot ones, but and the malleability and toughness of hot-rolled stainless steel strips are better.

Secondly, the thickness of cold-rolled stainless steel strip is ultra-thin, while the thickness of hot-rolled stainless steel strip is a bit thick.

Thirdly, for the surface finish quality, appearance and dimensional accuracy of cold-rolled stainless steel strips are better than those of hot-rolled stainless steel strips.

304(1.4301)/304L(1.4307)/304H(1.4948) STAINLESS STEEL

Stainless Steel Grade 304 is the standard 18/8 (18% chrome, 8% nickel) austenitic stainless steel. It is a non-magnetic alloy in the annealed condition, however, becomes magnetic as it is cold worked. It is the most ordinarily utilized of all stainless grades. T304 can be effortlessly welded and is the preferred for many deep drawn, spun or formed parts due to its high ductility.

Stainless Steel Grade 304L has oxidation resistance to a maximum temperature of 1650°F (899°C) continuous without considerable scaling. The maximum temperature for intermittent presentation is 1500°F (816°C). Since 304L is an additional low-carbon variety of 304 it can frequently be utilized in the “as-welded” condition (without annealing), even in severe corrosive conditions, except for applications indicating stress relief. 304L has good welding qualities and can be welded by all standard strategy; however, consideration should be paid to maintain a strategic distance from weld “hot cracking”. To relieve stress during severe forming or spinning welding may be followed by annealing.

Stainless Steel Grade 304H includes a high carbon content making the steel more suitable for utilization in applications where high temperatures are available. The benefit of this grade is that it is an austenitic chromium-nickel steel alloy as well as the greater carbon content distribute to increased tensile and yield strength. The material is recommended for utilizing in ASME pressure vessels in working service above 525° C because of the grade's heat resistant properties.

TISCO STEEL, known as a famous and largest stainless steel manufacturer in CHINA, was founded in the year of 1934, and the headquarters in Shanxi province.

TISCO STEEL has been focusing on developing stainless steel and other special steels for a long time. With the development of the enterprise, we set up a branch in Jiangsu Province called Jiangsu TISCO STAINLESS STEEL Co., Ltd. specialized in stainless steel products including further processing, sales and after-sales service. We also sell other kinds of steel products such as steel plate/coil and galvanized or PPGI etc.
We have set up exporting relations with more than 30 countries and areas such as USA, Brazil, Germany, UK, Arab, Turkey, Iran, UAE, Korea, Malaysia and Russia, etc. Our mission is providing excellent product quality and reputable service.
