UNS Number. SAE Number. 302 :S30200 A notable exception is in environments sufficiently corrosive to cause intergranular corrosion of welds and heat-affected zones on susceptible alloys. The Type 304L alloy is preferred for use in such media in the welded condition since the lower carbon level enhances resistance to intergranular corrosion

AISI 304 (S30400) Stainless Steel ::MakeItFrom

May 30, 2020 · AISI 304 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 304 is the AISI designation for this material. S30400 is the UNS number. Additionally, the British Standard (BS) designation is 304S15. And the AFNOR (French) designation is Z7Cn18-09. AISI 316 Stainless Steel Properties, SS 316 Grade Density 316L stainless steel (UNS S31603) is the low carbon version of AISI 316. SS 316 is better than SS 304 in terms of corrosion resistance, heat resistance and certain properties, but the price is higher than AISI 304, for more details, please check stainless steel grade 304 vs 316, and 316 vs 316L.

Corrosion Resistant Alloys - Corrosion Resistant Steel

Corrosion Resistant Steel. The best corrosion resistant steels in the world find their way into countless applications, from defense to aerospace, turbines and more. Acidic degradation can be easily staved off by the addition of chromium, which not only strengthens the alloy, but creates a passive oxide layer that essentially seals in the metal. Corrosion Resistant Alloys NITRONIC HASTELLOY INCONEL Economical, low alloy, corrosion resistant, abrasion resistant stainless steel. This is a popular replacement for carbon steel, due to the resistance to outside weather conditions. CARPENTER® alloy 20Cb-3® (UNS N08020) Ni 35, Fe 37, Cr 20, Cu 3.5, Mo 2.5

Hastelloy C-276 Nickel Alloy, UNS N10276, Alloy C276

Hastelloy C276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. High Alloy Stainless Steels for Fisher ValvesThis material is a superaustenitic stainless steel. Its corrosion resistance is higher than the duplex grades because its alloy content is higher. It has a high PREN (pitting resistance equivalency number) for superior resistance to chloride pitting and stress corrosion cracking. S31254 contains approximately 20% chromium, 18%

Introduction to the Unified Numbering System of Ferrous

The Unified Numbering System for Metals and Alloys (UNS) provides means of correlating many internationally used metal and alloy numbering systems currently administered by societies, trade associations, and those individual users and producers of metals and alloys.

Stainless Steel - Grade 416 (UNS S41600)

  • IntroductionKey PropertiesCompositionMechanical PropertiesPhysical PropertiesGrade Specification ComparisonPossible Alternative GradesCorrosion ResistanceHeat ResistanceHeat TreatmentGrade 416 steel is a free-machining stainless steel with a machinability of 85%, highest of all stainless steels. With most of the free-machining stainless steels, the machinability can be improved by adding sulphur, which leads to the formation of manganese sulphide inclusions. Addition of sulphur also reduces the formability, weldability and corrosion resistance of 416 steels to below that of grade 410. Because of their high machinability and low cost, grade 416 steels are available in highly tempered, hardened or unStainless Steel - Grade 410 (UNS S41000)
