JUNGJIN WONIL STAINLESS CO., LTD is a main maker and exporter of Stainless Steel 321 and Stainless Steel 321H Forged Fittings that are being planned according to the national and worldwide standard nature of crude materials and in this manner ensuring their strength and high caliber.
As the metal is molded amid the manufacturing procedure, the inner grain of our SS 321 Forged Fittings (WNR 1.4541) and SS 321H Pipe Fittings (WNR 1.4878) twists to take after the general state of the part. In the interim, we offer a comprehensive scope of stainless steel funnel fittings, for example, SS 321 union, SS 321H elbow, SS 321 tee, SS 321H cross, SS 321 areola, SS 321H bushing, etc.
Additionally refereed as UNS S32100 and UNS S32109, these SS 321 Seamless Pipe Forged Fittings and SS 321H Welded Tube Fittings, can further be redone regarding thicknesses and sizes according to the particular necessities given by our customers.
