Difference Between Stainless Steel 310 and 316 Flanges

Stainless Steel 310 Flanges



Stainless steel 310 Flanges are a medium carbon heat resilient with excellent resistance to oxidation under mildly cyclic conditions through 2000 F. Stainless steel 310 Flanges has high chromium & nickel contents which provide comparable corrosion resistance, superior resistance to oxidation & the retention of a larger fraction of room temperature strength than the mutual austenitic alloys like Type 304. Stainless Steel 310 Flanges can be used at cryogenic temperatures, due to excellent toughness up to -450 degree F, & low magnetic permeability.
Properties of Grade 310 Stainless Steel Flanges
SS 310 grades contain 25 percent chromium & 20 percent nickel, making it highly resistant to oxidation & corrosion. The high chromium & medium nickel content make capable of applications in reducing sulfur atmospheres containing Hydrogen sulfide. Stainless Steel 310 Flanges are widely used in moderately carburizing atmospheres, as encountered in petrochemical environments.
In common with other austenitic stainless steel, these grades cannot be hardened by heat treatment. They can be hardened by cold work, but this is rarely practiced. Type 310 is already fabricated by standard commercial procedures. Stainless Steel 310 can be welded using all of the common welding processes.
Characteristics of 310 Stainless Steel Flanges
·         Oxidation resistance to 2000 degree F
·         Moderate strength at high temperature
·         Resistance to hot corrosion
·         Strength & toughness at cryogenic temperatures
 Typical Applications for 310 Stainless Steel Flanges
·         Kilns
·         Heat Exchangers
·         Radiant Tubes
·         Muffles, retorts, annealing covers
·         Tube hangers for petroleum refining & steam boilers
·         Coal gasifier internal components
·         Saggers
·         Furnace parts, oven linings, fans, conveyor belts, rollers
·         Food processing equipment
·         Cryogenic structures
Stainless Steel 316 Flanges
Stainless Steel 316 Flanges are the standard molybdenum-bearing flanges, the molybdenum gives 316 Flanges better overall corrosion resistant properties, particularly higher pitting & crevice corrosion in chloride environments. It has excellent forming & welding characteristics. Grade 316 also has outstanding welding characteristics. The austenitic structure also gives these flanges exceptional toughness, even down to cryogenic temperatures.
Properties of Grade 316 Stainless Steel Flanges
Excellent in a range of atmospheric environments & many corrosive media – generally more resistant than 304. Subject to pitting & crevice corrosion in warm chloride environments, & to stress corrosion cracking above about 60 degrees C.
SS 316 grade is usually regarded as the standard “marine grade stainless steel”, but it is not resistant to warm seawater. In many marine environments, Stainless Steel 316 Flanges does exhibit surface corrosion, usually visible as brown staining which is particularly associated with crevices & rough surface finish.
Good oxidation resistance in intermittent service to 870 degrees C & in continuous service to 925 degrees C. Continuous use of 316 in the 425°-860° C range is not suggested if subsequent aqueous corrosion resistance is important.
Typical Applications for 316 Stainless Steel Flanges
·         Food preparation equipment particularly in chloride environments.
·         Laboratory benches & equipment.
·         Coastal architectural paneling, railings & trim.
·         Boat fittings.
·         Chemical containers, including for transport.
·         Heat Exchangers.
·         Threaded fasteners.
·         Springs.

Different Factors Used To Identify A Flange

Image
In this Blog, flanges manufacturer in India will discuss identifying a flange. Whether a flange will function correctly all goes back to whether the flange was the correct one for the job in the first place. A flange must fit in pipe joints just precisely in order for it to perform appropriately. A minor error in selecting a flange can affect an application resulting in a costly mistake. These 7 factors are all involved in selecting the perfect flange for the right application to maximize its functionality. Types It’s quite easy to recognize the type of flange by how it looks. First, identify the tops by determining whether a flange has a flat face, threaded bore, lap joint, weld neck, socket weld, or tongue & groove. Next is recognizing the bottoms by determining whether it has a flat face, which is wholly flat or a  raised face  which is a slightly raised section on the face of the flange. Size The size of a flange is comprised of factors that includ...
