گرید ۴۱۰ استنلس استیل حاوی 11.5 درصد کروم است که مقاومت در برابر خوردگی خوبی را فراهم میکند.

Grade 410 stainless steels are resistant to hot gases, steam, food, mild acids and alkalies, fresh water and dry air. These steels obtain maximum corrosion and heat resistance through hardening. However, grade 410 steels are less corrosion resistant than austenitic grades and grade 430 ferritic alloys containing 17% chromium. Smooth surface finish offers improved performance of steels.

Welding :

Grade 410 steels can be welded using all conventional welding techniques, but the materials should pre-heated at 150 to 260 °C followed by post-weld annealing treatment, to mitigate cracking. Grade 410 welding rods are recommended for tempering and post-hardening. In the "as welded" conditions, grade 309 filler rods can be used to achieve a ductile joint.

According to AS 1554.6 standards, grade 309 electrodes or rods are preferred for welding 410 steels.

در نتیجه برای اتصال این نوع استنلس به لوله X65 از گرید 309 استفاده میشود.

ER410. This 12 Cr alloy (wt. %) is an air-hardening steel. Preheat and postweld heat treatments are required to achieve welds of adequate ductility for man engineering purposes. The most common application filler metal of this type is for welding alloys of similar composition. It also used for deposition of overlays on carbon steels to resist corrosion, erosion, or abrasion.
