BALANCE

Stainless Steel 410 Pipe Fittings and Flanges offer both exceptional wear and corrosion resistance. Stainless Steel 410 Pipe Fittings and Flanges can be heat treated to obtain a wide range of mechanical properties and can be further enhanced by a series of processes.

Physical properties

Stainless Steel 410 Pipe Fittings and Flanges combines superior wear resistance of high carbon alloys with the excellent corrosion resistance of chromium alloys. SS 410 fittings possess magnetic properties in both the annealed and hardened conditions.

Specification of Flange 

The specified ASTM Standard Specification for Wrought Martensitic SS 410 Flanges is ASTM A182 with manufacturing standard such as ANSI/ASME B16.5, B16.48, BS4504, B 16.47 Series A & B, BS 10, EN-1092, DIN, etc.

According to application and uses in pipes and tubes SS 410 flanges are broadly grouped into different sort, for example, Welding Neck Flange(WNF) & Long Welding Neck Flange(LWNF), Slip-on Flange(SOF), Lap Joint Flange(LJW), Blind Flange, Socket Welding Flange (SWF), Threaded Flange(THW), Plate Flange.

SS 410  Flange for the most part has different  face type, for example, Flat Face (FF), Raised Face (RF), Ring Type Joint (RTJ), blind flange, with various class rating as 50 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS, DIN Standard ND-6,10, 16,din 2.4856 , 25, 40 & ANSI B16.5.

Specification of Fittings

The Specification for Wrought Martensitic SS 410 Fittings is ASTM A403, having Specific manufacturing Standards as ASME/ANSI B16.9, ASME B16.28, MSS-SP-43.

SS 410 Fittings that are categorically available are Elbow, Reducer, Tee, Coupling, Bend, Stub End, Cap, Nipple, Washer, Cross, Union etc which are available in different  types such as Welded, Seamless and Fabricated having thickness range from 5s, 10s, 40s, 80s, 10, 20, 40, STD, 60, 80, XS, 100, 120, 140, 160, XXS available with NACE MR 01-75

Application

Grade 410 or UNS S41000 Flanges and Fittings provide good corrosion resistance to air, water and some chemicals and also resistance to food acids. Whereas these SS410 flanges are satisfactory resistance to nitric acid, concentrated sulphuric acid, dilute acetic acid and naphtha. 

SS 410 pipes and tubes are used in large scale industries such as Sugar Industries, Chemical industries, Petrochemical Industries, Pharmaceutical plants, Fertilizer and Oil plants, Textile machineries, Cement industry etc.
