SS420 Stainless Steel Strip is a high-performance martensitic stainless steel with a high carbon content, so it has high hardness, excellent wear resistance and corrosion resistance. It is widely used in various precision machinery, bearings, electrical, equipment, instruments, meters, transportation vehicles and household appliances. In addition, SS420 Stainless Steel Strip also has good weldability and fatigue strength, and is suitable for high-load application scenarios such as engine parts in automobile manufacturing and structural parts in aerospace. At the same time, SS420 Stainless Steel Strip can meet food grade standards and is suitable for food tableware and hospital equipment. In short, stainless steel Strip 420 is widely used in many fields due to its excellent performance.

SS420 Stainless Steel Striphas high strength and high hardness, and is suitable for manufacturing parts that need to withstand high loads. At the same time, its chromium content is above 12%, with good corrosion resistance, and can play a role in seawater environments and some chemical equipment. In addition, SS 420 also has good weldability and certain machinability, and can be processed by various welding methods and hot and cold processing processes.
In terms of application, SS420 Stainless Steel Strip is widely used in the manufacture of wear-resistant parts such as knives, measuring tools, and molds due to its excellent hardness and wear resistance, such as kitchen utensils, scalpels, hair clippers, calipers, micrometers, as well as plastic molds, rubber molds, etc. In addition, it is also commonly used to manufacture parts that are resistant to atmospheric, water vapor, water and oxidizing acid corrosion, such as bearings, precision machinery, etc., and is also widely used in electrical appliances, equipment, instruments, meters, transportation vehicles, household appliances and other fields.
Ningbo Huali Steel has introduced advanced machinery from abroad, equipping its production lines with top-tier manufacturing equipment. Certificates we are able to provide include ISO9001, SGS, mill certificates and more.
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.
Our production technology can make the SS420 Stainless Steel Strip absolutely flat, making the finished product less likely to bend or deform.
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 arrive in safe condition.
