Product Description

Product Description

Introduction

LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
 

254 SMO is a high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content. It demonstrates outstanding resistance to pitting, crevice corrosion stress cracking, and corrosion fatigue uniform corrosion. 254 SMO is substantially stronger than the common austenitic grades, with strength nearly twice that of 300 series stainless steel. It is also characterized by high ductility and impact strength. With high levels of chromium, molybdenum, and nitrogen, 254 SMO is frequently used in high chloride environments, such as brackish water, seawater, pulp mill bleach plants, and other chloride process streams. In some applications it has even been found to be a more cost effective substitute for high nickel and titanium alloys.
Duplex Stainless 254 SMO Applications

Due to its high levels of molybdenum and nickel, Alloy 254 SMO is frequently used in high chloride environments. Examples of applications that call for the used of Alloy 254 SMO include:
▪ Petroleum production
▪ Saltwater handling
▪ Food and chemical processing equipment
▪ Pulp mill bleach systems
▪ Flue gas desulphurization scrubbers
▪ Tall oil distillation columns
▪ Offshore oil & gas production equipment
▪ Desalination equipment

254SMO Duplex Stainless Sheet Welding

Welding of stainless steel grade 254 SMO requires filler material without which it results in poor strength properties. Filler metals such as AWS A5.14 ERNiCrMo-3, and alloy 625 are recommended. Electrodes used in the process, have to match with AWS A5.11 ENiCrMo-12.

254SMO Duplex Stainless Sheet Heat Treatment

Forging, upsetting and other operations relating to this material can be performed at 982 - 1149°C (1800 - 2100°F). It is recommended that temperatures do not exceed this range as it would result in scaling and reduction in the workability of the material. To re-attain maximum corrosion resistant properties, it is advisable to perform post-process annealing.
Stainless steel grade 254 SMO does not respond to heat treatment. Hardening is possible only through cold reduction.
