Product Description

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


Cold-rolled stainless steel strip refers to a product that is manufactured through a cold rolling process applied to stainless steel coils.
Stainless steel strip coil is rolled by cold rolling mill at room temperature.
The conventional thickness is between 0.1mm and 3mm, and the width is between 100mm and 2000mm.
Cold rolled stainless steel strip has many advantages such as smooth and flat surface, high accuracy, good mechanical properties, and can be rolled or processed into coated steel plates.
The sequence of the production process is pickling, normal temperature rolling, process lubrication, annealing, leveling, precision cutting, and packaging.
Cold-rolled stainless steel strip is widely used in industries such as automotive, aerospace, construction, electronics, and manufacturing.
The precise dimensions, consistent thickness, and high-quality surface finish of cold-rolled stainless steel strip make it desirable for applications where tight tolerances and aesthetic appearance are crucial.
Compared to hot-rolled stainless steel strips, cold-rolled strips generally exhibits better dimensional control, improved surface quality, and higher strength.
However, it is important to note that cold-rolled stainless steel strip typically has a narrower range of available sizes and may be more expensive due to the additional processing steps involved.
Overall, cold-rolled stainless steel strip offers excellent properties and versatility, making it a preferred choice in various industries where high-quality, precision-engineered components are required.


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.

What is the difference between 304 and 304DDQ stainless steel?

Compared with 304, the CR content of 304DQ is increased by half to one, and the polishing is better. Compared with 304, the content of 304DDQ has not changed. The content of NI is increased by half to one, and the deep drawing and deep drawing are better. “Soft material” but poor polishing performance.

304DDQ stainless steel uses a special process to increase the chromium content of 304 stainless steel by 2 points (304 steel plate is 18/8, 304 DDQ is 18/10), which means that the content of nickel (Ni) in 304 stainless steel is 18%, and chromium ( The content of Cr) is 8%; the content of nickel (Ni) in the improved 304DDQ stainless steel is 18%, and the content of chromium (Cr) is 10%; the steel plate has high brightness, no discoloration, and beautiful appearance, but also has the best Good ductility, toughness, and corrosion resistance.
