Stainless steel 420J2 is a medium carbon martensitic stainless steel that achieves high strength, hardness and corrosion resistance through quenching and tempering heat treatment.
The selection of stainless steel materials, thickness and width design for cylinder gaskets are centered around three core requirements: sealing reliability, temperature and pressure resistance, and compatibility with engine structure.
Razor blades are an indispensable core component of modern electric razors, directly affecting shaving performance, comfort, and service life.
The 301 stainless steel strip has excellent elasticity and toughness, and its strength increases after cold processing. The rings made of this material can firmly grip even after multiple openings and closings, thereby sealing the dry bags and preventing the contents inside from getting wet.
As a key branch of stainless steel, 304L stainless steel welded pipe, with its unique low-carbon design (carbon content ≤ 0.03%), demonstrates irreplaceable value in industries with stringent corrosion resistance requirements, such as chemical, petroleum, and food processing.
On March 7, 2025, the Ministry of Strategy and Finance of South Korea issued Announcement No. 2025-72, imposing a four-month temporary anti-dumping duty on hot-rolled stainless steel plates (Stainless Steel Plate) originating in China with a thickness of not less than 4.75 mm and a width of not less than 600 mm.
