YC INOX is a leading supplier of stainless steel welded pipes in the world. We are top 5 stainless steel welded pipe/tube producer worldwide rated by Austria SMI (Steel Market Intelligence) magazine. We provide world class stainless steel pipes according to international standard of ASTM A312/A312M, which is referring to straight-seam welded pipe and welded Austenitic stainless steel pipe for general corrosive environment.
YC INOX supplies commercial stainless steel material grades including TP304, TP304L as well as TP316L. These 3 different grades are classified as 300 series in Austenitic stainless steel category. The most common Austenitic stainless steel of all stainless steel is TP304 which is extensively used. Referring to TP316L grade, it contains with molybdenum, that resulted with better performance of resistance to acids, such as pitting and crevice corrosion.
ASTM A312 stainless steel pipe can be used for structural, piping, petro-chemical as well as machinery industry applications, which usually require high strength, toughness and excellent corrosion resistance. YC INOX offers outside diameter range from sizes 1/4" up to 84" for stainless steel pipe of industrial application, and schedule 5S, 10S, 40S, 80S, STD and XS in wall thickness (WT). Other nominal diameter and wall thickness may be available subject to the approval of vendor and purchaser.
In terms of packaging, YC INOX offers two options, one is steel crate and the other is bundle package. Customers can choose the package as per their needs for stainless steel pipes.
Professional team with excellent after-sales service:
- Punctual delivery time makes stock controlling well.
