SUS 420J1 Stainless Steel Analysis reveals many highlights of this steel

In terms of characteristics, SUS 420J1 Stainless Steel is a martensitic stainless steel with high strength and hardness, with a hardness of up to about HRC50, which can withstand a certain degree of friction, wear and tear, and excels in scenarios that require wear resistance. At the same time, it has moderate corrosion resistance, compared with ordinary carbon steel, in the atmosphere, fresh water and other media have better rust resistance, can resist daily oxidation erosion.
In terms of advantages, SUS 420J1 Stainless Steel Analysis shows that it has good machinability and is easy to be shaped by cutting, grinding, heat treatment and other processes. In the field of knife manufacturing, its heat-treatable reinforcement characteristics can precisely regulate the hardness to create a sharp and durable blade, meeting the needs of different knives such as chef's knives and outdoor knives in terms of sharpness and abrasion resistance. Moreover, it is relatively low-cost, compared with some high-end stainless steel, more economic advantages in mass production.
Talking about the scope of application, in the hardware industry, SUS 420J1 Stainless Steel is used in a large number of production of various types of fasteners, such as screws, nuts, etc., with the strength and corrosion resistance to ensure a solid connection. In the kitchenware industry, in addition to knives, some kitchen gadgets, such as shredders, scissors, etc., are also often used, which is durable and easy to clean. In the shell manufacturing of medical and cosmetic instruments, its clean appearance, a certain degree of rust resistance in line with health standards, while the cost is controllable, providing practical options for instrument manufacturers.
