The 304 cold rolled precision stainless steel coil is a very common type of stainless steel and belongs to the austenitic stainless steel family. It is designated differently in various countries, such as EN1.4301, DIN1.4301, AISI 304, and SUS304. High Cr-Ni series steels have been developed by increasing the content of Cr and Ni and adding elements such as Mo, Cu, Si, Nb, and Ti based on this stainless steel. 304 stainless steel has always played the most important role among stainless steels, accounting for approximately 70% of the total production and usage of stainless steel. By altering different elements, 304 stainless steel can achieve various properties: adding Mo improves pitting and crevice corrosion resistance; reducing C or adding Ti and Nb reduces susceptibility to intergranular corrosion; adding Ni and Cr enhances high-temperature oxidation resistance and strength; adding Ni improves stress corrosion resistance; and adding S and Se enhances machinability and surface precision of components. The 304 cold rolled precision stainless steel coil is widely used in industries such as industrial and furniture decoration, as well as the food and medical sectors.
| GRADE | Chemical Composition | ||||||
| C | Si | Mn | P | S | Ni | Cr | |
| % | % | % | % | % | % | % | |
| 304 | ≤0.08 | ≤1.0 | ≤2.00 | ≤0.045 | ≤0.030 | 8.00/10.50 | 18.00/20.00 |
Compared to austenitic stainless steels, 304 cold rolled precision stainless steel coil offers higher strength, superior resistance to intergranular corrosion, and relatively better resistance to chloride stress corrosion.
Excellent corrosion and high-temperature resistance: making it suitable for high-end stainless steel tableware, bathroom fixtures, and other applications.
High temperatures: making it widely used in industrial and furniture decoration industries, as well as the food and medical sectors.
Good processing performance and weldability: making it commonly used in plate heat exchangers, metal bellows, kitchenware, mufflers, molded products, medical instruments, and more.
Ningbo Huali Steel has introduced advanced machinery from abroad, equipping its production lines with top-tier manufacturing equipment.
The American imported twenty series Sendzimir high precision reversible mill is capable of speeds up to 650 m/min, with automatic series proportioning, and is equipped with an AGC automatic downward deflection correction system that ensures that overall tolerances are maintained to within ± 0. 002 mm.
Twenty-three rolls tension leveler with automatic online surface inspection, defects alarm, and remote defects record function to ensure accurate production process and instant record of status.
Used to clean oil and other stains from the surface of 301 cold rolled precision stainless steel coil to send them to the annealing furnace or factory.
As for packaging, we offer standard packaging (waterproof paper and steel belt packing) and wooden box packaging, as well as customized packaging solutions tailored to our clients' specific requirements.
Our dedicated loading team ensures meticulous handling of every shipment. Each container is securely reinforced with wood and wire rope to guarantee that your goods (301 cold rolled precision stainless steel coil) arrive in safe condition.
