Magnetic! Welding material with the highest class of hardness among all stainless steel and heat-resistant steel.
"Ferritic stainless steel" has magnetic properties and requires caution against cold cracking during welding due to its susceptibility to weld cracking. Typically, preheating is necessary. In steel grades with reduced carbon and nickel, the susceptibility to cracking is low, and when using γ-type welding materials, preheating is not required (e.g., SUS410L). The heat-affected zone of the weld is hard and brittle, but post-treatment can restore toughness and ductility. In steel grades with reduced carbon and nickel, there is toughness even without post-welding treatment. 【Lineup】 ■SUS440C For more details, please contact us.
