What is martensitic stainless steel?
Martensitic stainless steel is a stainless steel alloy containing carbon less than one percent. Instead, martensitic stainless steel consists mainly of iron and chrome and a smaller amount of nickel, copper and other metals. This special metal mixture gives this material several advantages over traditional carbon steel, including strength and corrosion resistance. Martensitic stainless steel is named after its inventor, German scientist Adolf Martens, who developed this particular form of steel at the end of the 19th century. In some parts of the world, this material is known as Staybrite® after an early brand product.
The amount of chrome used to produce martensitic stainless steel determines the properties of metal and its degree or quality. In general, this product contains 12 to 14 percent of chrome, with higher amounts used to produce higher degrees. It may also include lead, copper and other metals known by its strength or corrosion. The higher the chromia content, the better the steel is able to withstand rust and corrosion. NMore signs can be used for tools, building facades and car details, while higher grades are required to produce jewelry, food storage and weapons.
To make martensitic stainless steel, manufacturers mix the desired mixture of metal alloys at high temperature. As it solidifies, the steel is subject to rapid cooling or extinguishing. During cooling, the steel can be placed in the tulle, oil or even water depending on the required properties. This combination of heating and cooling helps to balance hardness, corrosion resistance and internal strength of this material.
Heating and extinguishing steel helps to increase its resistance and wear resistance and leave the material very hard. Adding chrome to any steel alloy gives it a natural level of resistance and corrosion. This means that this material can be used outdoors or in a marine environment without much or maintenance. On the differenceL From many other metals, this material remains strong at high temperature levels, although it can be weaker at freezing temperatures. Martensitive stainless steel is highly machinable and can be welded using standard equipment and techniques.
Since the steel is stiffened by heating and extinguishing, it also becomes more fragile. This means that steel can withstand wear and heavy use, but is vulnerable to cracks or breaking if exposed to a high level of shock or strong impact. In general, manufacturers must work on the balance of hardness and fragility at the best level for each application.
