SPECIALTY STAINLESS
Alloy description
304/304H is an austenitic chromium-nickel alloy known to be among the most adaptable and widely applied stainless steels in the 300 series. The higher carbon content in 304H makes for an amplified tensile and yield strength.

Stainless 310S/310H is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditions through 2000°F. Its high chromium and nickel contents provide comparable corrosion, superior resistance to oxidation and the retention of a larger fraction of room temperature strength than the common austenitic alloys like Type 304.

Alloy description
317L is a molybdenum bearing, low carbon content “L” grade austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels. The low carbon provides resistance to sensitization during welding and other thermal processes. 317L has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments.

Alloy description
347/347H is an austenitic chromium steel containing columbium often used in refineries, high temperature chemical processing, and high temperature steam service. This columbium bearing steel is not sensitive to intergranular corrosion after heating within the range of carbide precipitation but elevated properties may be achieved through cold reduction.

Alloy description
904L is a high-alloy austenitic stainless steel with low carbon content. The grade is intended for use under severe corrosive conditions. It was originally developed to resist corrosion in dilute sulfuric acid and has been proven effective in this application over many years. Structurally, 904L is fully austenitic and is less sensitive to precipitation ferrite and sigma phases than conventional austenitic grades with high molybdenum content. 904L has a good resistance to general corrosion, particularly in sulfuric and phosphoric conditions.

254 SMO® is an austenitic steel designed for maximum resistance to pitting and crevice corrosion. With high levels of chromium, molybdenum and nitrogen, 254 SMO® is especially suited for high chloride environments such as brackish water, seawater, pulp mill bleach plants and other high-chloride process streams. In new construction, 254 SMO® has been found in many cases to be technically adequate and much less costly substitute for nickel-based alloys and titanium. 254 SMO® is readily fabricated and welded.

Super Duplex 2507 is a nickel-molybdenum-chromium alloy designed for applications demanding outstanding strength and corrosion resistance. The nitrogen, chromium, and high molybdenum content results in excellent resistance to crevice corrosions and chloride pitting. Super Duplex 2507 is often found in offshore platforms, heat exchangers, chemical processing, seawater equipment, and in the petrochemical industry.

NICKEL ALLOYS
Alloy description
Nickel 200/201 are solid solution strengthened, commercially pure wrought materials with good mechanical properties over a wide range of temperatures and excellent resistance to many corrosives, in particular hydroxides. Nickel 201 was a modification of Nickel 200 to control carbon (.02 max) which keeps it from being embrittled by intergranular precipitates at temperatures of 600°F to 1400°F in many processes. Typically, the elemental restrictions of both Nickel 200 and Nickel 201 are combined into one, dual-certified chemistry resulting in a single alloy with the desired characteristics of both alloys.

Alloy 625 is a corrosion and oxidation resistant nickel alloy that is used both for its high strength and outstanding aqueous corrosion resistance. Its outstanding strength and toughness is due to the addition of niobium which acts with the molybdenum to stiffen the alloy’s matrix. Alloy 625 has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions. This alloy resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion.
