As an acclaimed undertaking of the business, JUNGJIN WONIL STAINLESS CO., LTD is included in offering an unfathomable cluster of Stainless Steel 304/304L/304H Buttweld Fittings as a maker, exporter, stockiest and supplier to our household and worldwide customers. Stainless Steel 304L is the low carbon rendition of 304. It doesn't require post-weld toughening as is widely utilized as a part of substantial gage segments (over around 6mm). Stainless Steel Grade 304H with its higher carbon content discovers application at elevated temperatures.
Regarding diverse evaluations, we offer these Stainless Steel Pipe Fittings in various sorts, for example, SS Seamless Butt weld pipe fittings, SS Welded Butt weld pipe fittings, SS Elbow (45deg, 90deg, 180deg), SS Equal and Unequal (diminishing) Tees, SS Equal and Unequal (lessening) Cross, SS Concentric and Eccentric Reducer, SS Long and Short Stubends, and SS Pipe End Caps.
As for national and global nature of crude materials, we likewise offer these SS 304/304L/304H Buttweld Fittings in tweaked sizes and thicknesses according to particular requests by our regarded customers at business sector driving costs.
