Product Description

Product Description

 

Introduction

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

Stainless steel grade 304 is the most commonly used stainless steel. Stainless steel grade 304N has better corrosion resistance than grade 302, and is mostly non-magnetic in nature; however when cold worked it acquires a slightly magnetic quality.
 

 Stainless Steel 304N Applications

Grade 304N stainless steel is widely used in the following applications:
▪ Valves
▪ Oil well filter screens
▪ Cooling coils
