Stainless steel
Chemical composition
: Carbon: .~. Silicon. Manganese. Sulfur. Phosphorus. Chromium:.~. Nickel allowed Contains. Molybdenum: can be added
Mechanical properties
: Internal stress ( /) Tensile strength ( /) ( )
Characteristics: high hardness and good wear resistance, when grinding, Its disadvantages are that it is sticky and heats up quickly, but it is easier to sand than any carbon steel and is much easier to cut with a hand saw.
The annealing temperature is very low, the hardness is usually 100%, and the corrosion resistance and toughness are very strong. It is now more widely used in hand-made knives and high-quality factory-made knives.
Features and applications: It has the highest hardness among all stainless steels and heat-resistant steels. It is a steel type used in nozzles and bearings to improve the easy cutting performance of steel. Used for automatic lathes. Martensitic stainless steel has the same characteristics of hardening through quenching as ordinary alloy steel, so a wide range of different mechanical properties can be obtained by selecting the grade and heat treatment conditions.
Stainless steel contains carbon. This kind of steel has good rust resistance. It is a high-quality stainless steel currently used in the high-end batch tool market. Its strength and sharpness are even higher than that of stainless steel. Its chromium content is as high as -, and it is the second most commonly used stainless steel. Stainless steel
(second only), was also the first stainless steel to be accepted by knifemakers, and has remained popular, especially after the sub-zero treatment process was developed, which enhanced the toughness of the steel.
Uses: ASSAB special steel has high hardness after quenching and good corrosion resistance (magnetic). Tableware (knives) and turbine blades have higher hardness than steel after quenching (magnetic). Knife blades, nozzles, valves, Board ruler, cutlery (scissors).
