As an acclaimed undertaking of the business, Jainex metal is included in offering an unfathomable cluster of Stainless Steel 304/304L/304H Flanges 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 Flanges in various sorts, for example, SS Slip On Flanges, SS Blind Flanges, SS Weld Neck Flanges, SS Socket Weld Flanges, SS Spectacle Blind Flanges, SS Screwed/Threaded Flanges, SS Reducing Flanges, and SS Ring Type Joint Flanges (RTJ). In the interim, our costs of such spines are set remembering customers prerequisite.
As for national and global nature of crude materials, we likewise offer these SS 304/304L/304H Flangesin tweaked sizes and thicknesses according to particular requests by our regarded customers at business sector driving costs.
