We are a manufacturer and exporter of 1.4435 Stainless Steel Seamless Pipe 316LMo
1.4435 stainless steel is an austeniticy high corrosion resistance material. This grade is written as 1.4435 or 316LMo or X2CrNiMo18-14-3 according to EN norm.
1.4435 stainless usually compared with 316L (1.4404) stainless steel grade. 1.4435 material has a higher content of chromium, nickel and molibdenium and because of these elements, it is more resistant to corrosion then 316L (1.4404) grade. 1.4435 is ready in Birçelik warehouse and 1.4435 grade is not magnetic. This grade is used in corrosive enviorements and if 316L grade is not enough, 1.4435 stainless steel could be a very good alternative material. 1.4435 material usually used in petrochemical industry, pharmaceutical industry, chemical production plants and automotive industry. This grade is not a heat resistant grade and it is not suitable to use this grade in high temperatures.
316LMo is an acid-resisting austenitic CrNiMo-Steel with 18% Cr, approx. 14% Ni and at least 2.5% Mo. Due to the increased Mo-content, this material has a significantly improved corrosion resistance compared to other CrNi-Steels. 316LMo is particularly strong against organic and inorganic acids as well as against halogen-containing media. Furthermore, it is also less susceptible to pitting. Its very low carbon content also improves the resistance to intergranular corrosion, allowing the use of this steel at temperatures up to 450 ° C in continuous operation. 316LMo can also be very well polished, very good deformable and can be easily welded.

1.4435 Equivalent Grades
| Standard | Grade |
|---|---|
| EN | 1.4435 (X2CrNiMo18-14-3) |
| UNS | S31603 (close to 316L but with higher Mo, often called “high Mo 316L”) |
| ASTM | 316L Modified (Special quality) |
| Werkstoff Nr. | 1.4435 |
Compared with 316L (1.4404), 1.4435 has higher molybdenum content → better pitting & crevice corrosion resistance, especially in chloride-rich environments.
