Ferritic & Martensitic Stainless Steel
Ferritic and martensitic stainless steel are two types of stainless steel that have different crystal structures. Austenitic and ferritic stainless steel is magnetic, has good corrosion resistance, and is used in applications such as automotive exhaust systems and appliances. Martensitic stainless steel is known for its hardness and is used in items like knives, blades, and turbine parts.
Types of ferritic stainless steel & Martensitic Stainless Steel
Yes, both ferritic and martensitic stainless steel can be welded, but they require different welding techniques and may require preheating and post-weld heat treatment to reduce the risk of cracking.
Ferritic stainless steel has a lower thermal conductivity and higher thermal expansion coefficient than austenitic ferritic stainless steel, which makes it more susceptible to cracking during welding. Therefore, preheating the material to a certain temperature before welding and controlling the heat input during welding is necessary to reduce the risk of cracking.
Martensitic stainless steel has a higher carbon content than ferritic materials stainless steel, which makes it more susceptible to cracking. Therefore, preheating the material to a higher temperature before welding is necessary, and the heat input during welding needs to be minimized to prevent overheating.
In general, welding of ferritic and martensitic stainless steel should be carried out by experienced and skilled welders following the proper welding procedures to avoid cracking and achieve good weld quality.
