Zeron 100 is highly resistant to corrosion in a wide range of organic and inorganic acids. The copper content gives excellent resistance to corrosion in many oxidising acids. This alloy is also highly resistant to strong alkalis.

We are manufacturers of ASTM A182 Duplex UNS S32750 / S32760 Flanges show enhanced pitting corrosion resistance in saline environments, brackish waters, bleaching operations, and selected food processing applications.

Duplex UNS S32205 fasteners are widely used in construction and other industrial applications. We offer these types of fasteners in differenut thicknesses and tolerance limits for a variety of industrial applications.

Super Duplex stainless for e.g. alloy UNS S32750, has a mixed microstructure of both austenite as well as ferrite in an equal or 50/50 ratio.

S32760 super duplex stainless steel is more resistant to pitting and crevice corrosion than regular austenitic or duplex stainless steels and is suitable for use in corrosive environments. This is due to higher additions of chromium, molybdenum and nitrogen.

ASTM A815 specification covers two general classes, WP and CR, of wrought ferritic, ferritic/austenitic, and martensitic stainless steel fittings of seamless and welded construction. Class WP fittings are subdivided into four subclasses: Classes WP-S, WP-W, WP-WX, and WP-WU. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products.
Teel Industry has grown in the past few decades and there are a variety of products available in the market. ASTM A815 UNS S32750 Pipe Fittings are one of those products and are available in various sizes, shapes, and dimensions. ASTM A815 UNS S32760 Pipe Fittings are designed to be resistant to corrosion and are said to have perfect weldability. These Super Duplex S32750 Buttweld Fittings are resistant to erosion corrosion and fatigue. They have a mixed microstructure of 50% austenitic and 50% ferrite.

Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation.

Due to the excellent physical and mechanical properties of Super Duplex, the quality of Super Duplex steel fasteners can meet the high demands of the gas, oil and marine industries.

For duplex S31803 nuts, 2 minutes to 3 minutes per mm of wall thickness at temperatures around 1080 degrees Celsius is sufficient to achieve a balanced austenite/ferrite ratio. After annealing, it is recommended to cool these Duplex S32205 nuts as soon as possible.

Duplex steel UNS S32205 fasteners are used in the pulp and paper industry such as digesters, bleach plants and stock handling systems. Also known as WNR 1.4462 fasteners, they are developed and designed in our infrastructure to international quality standards to the highest quality standards.

2507 has high resistance to stress corrosion cracking (especially chloride stress corrosion cracking), high energy absorption, high strength, and erosion. Essentially, and the Duplex alloys are a compromise.

Super Duplex 2507 has more than twice the strength of conventional austenitic stainless steels in the annealed condition.

For many applications where 300 series stainless steel is susceptible to chloride stress corrosion cracking, 2205 duplex stainless steel is a cost-effective solution. Stress corrosion cracking occurs when stainless steel is subjected to tensile stress while in contact with solutions containing chlorides. Elevated temperatures also increase the susceptibility of stainless steel to stress corrosion cracking.

2205 has good solderability. The motivation for welding dual-phase steels is to maintain the corrosion resistance, toughness and strength of the base metal in the weld metal and heat affected zone.

The corrosion resistance comes from the addition of alloying material, mostly the chromium content. The ASTM A790 Pipes are resistant to pitting corrosion and crevice corrosion.

Super Duplex UNS S32750 /F53 Flanges are made from a super duplex stainless steel grade that has 24% chromium, 3% molybdenum, 6% nickel and carbon, manganese, silicon, sulfur, phosphorus, nitrogen and iron in the composition.

Super Duplex Steel UNS S32760 are dual phase austenitic-ferritic duplex fasteners manufactured from alloy containing chromium, nickel and molybdenum with restricted carbon content and minimum PREN42. Zeron washers have high strength, resistance to pitting, stress corrosion cracking, erosion and corrosion fatigue, crevice corrosion resistance.

ASTM A1082 specification alloy S31803 fasteners have higher pitting and crevice corrosion than stainless steel alloy 316. Due to its higher corrosion resistance, alloy grade UNS S31803 is able to exhibit better fatigue strength than other commonly used austenitic stainless steel grades in environments containing corrosive media.

Alloy 2205 gets the name Duplex because it is composed of two different types of grains. 40-50% of its grain structure is austenite and 50-60% of it is ferrite. It is closely related to, but much more popular than Alloy 255. In most environments, it surpasses 317L in crevice corrosion resistance. 2205 Duplex excels in chloride environments and resists hydrogen sulfide. 2205 Duplex has almost twice the strength of 316L. Due to the lower nickel and molybdenum content, it is less costly than Alloy C276. Among the places where 2205 Duplex is used include pressure vessels, heat exchangers and scrubbing systems.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

S31803 Duplex Steel is a 22% chromium duplex (austenitic/ferritic) steel with moderate to good strength and good general corrosion/stress corrosion/cracking resistance.
