Steel grades of 18CrNiMo7-6

18CrNiMo7-6 is a case-hardening steel known for its exceptional toughness. There are several variants of this steel that have stringent cleanliness requirements and possess narrower composition ranges compared to the standard version. One specific variant, designated as IQ (isotropic quality), is produced to have an extremely low number of elongated sulfide inclusions, resulting in more isotropic properties. The high level of oxidic cleanliness in this variant allows it to meet the same demanding cleanliness standards as re-melted qualities.Grade 159A: This variant has a low sulfur content and is designed to meet high cleanliness requirements.Grade...

Properties of LEAN DUPLEX UNS S32101 - ALLOY 1.4162 - LDX 2101

ALLOY 1.4162 / LEAN DUPLEX UNS S32101 / LDX 2101 MATERIAL DESCRIPTION LDX 2101 is a low Ni-alloyed duplex with balanced chemistry of chromium, molybdenum and nitrogen content to achieve good resistance to localized and uniform corrosion. The duplex microstructure contributes to the high strength and high resistance to stress corrosion cracking. Duplex steels have good weldability. Due to risk of embrittlement, LDX 2101 should not be used at temperatures above 250°C. Very price stable high strength alloy.LDX 2101 is a low-nickel, nitrogen enhanced lean duplex stainless steel developed for general-purpose use. The austenitic-ferritic (duplex)...

CF-3M: Corrosion Resistant Alloy Property Data

Stainless Steel SA351 CF3M, Butterfly valveDESCRIPTION CF-3M is a Fe-Cr-Ni-Mo alloy that is the cast equivalent of wrought, low carbon, AISI 316L stainless steel. The low carbon content of the alloy results in greater resistance to sensitization of the welds. Consequently, it is most commonly used in applications where post-weld heat treatment cannot be applied. Optimum corrosion resistance is reached after solution annealing at 1900 to 2050oF followed by rapid cooling. It has good resistance to organic acids and salts, sulphuric and sulfurous acids, phosphoric and phosphoric-sulphuric-hydrofluoric acid mixtures, sulfate and sulfite liquors,...
