Generally, 300 series of stainless grades contain chromium, nickel, and molybdenum. These steels aren't attracted to magnets. They're strong stainless, but not as easily welded as the 300 series. The SAE system of numbering uses a 1-letter + 5-digit UNS number code to designate stainless steel. Today's popular knife steels Below are the most common steels found in knife blades today. Note that to qualify as a true stainless steel there must be at least 13% chromium. In 2000 the production changed to Seki. 409CB The 400 series knives, etc., keep a nice sharp edge, the 300 series don't corrode so easily and they are softer, due to the nickel, one assumes. One reason for this is that the sulfides, elongated in the direction of working, intersect this surface. While this is great for people with serious nickel allergies, it does mean that stainless steel is far more likely to tarnish and corrode over time. The 400 series precipitation-hardening and free-machining stainless steels are best evaluated in a cabinet capable of maintaining 100 percent humidity (samples wet) at 95F (35C) for 24 hours. While most grades have a designation, newly developed exclusive grades may be named by their owners and not have any SAE code. There is a series of stainless steels that ranges from SAE 100 - 600. 400 series stainless steel has a strong resistance to high temperature oxidation, and compared with carbon steel, its physical properties and mechanical properties have been further improved. Typically, chromium will make up 12% of the ingredients and increase the strength of the knife. This steels comes from the 400 series of steels, which is popular among knife makers due to high corrosion resistance and easy sharpening. Get Quote. Product Details.
