304 Stainless Steel Marine Pump Cover

Introduction

304 stainless steel is one of the most widely used chromium - nickel stainless steel, as a widely used steel, It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other thermal processing, no heat treatment hardening phenomenon (use temperature -196℃ ~ 800℃). Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. It has good machinability and weldability. In addition, we can process and customize according to customer's drawings and material requirements.
