Precision Forged Stainless Steel Sheet Industrial Strength & Heat Resistant 300 Series 400 Series

Products Specification

Forged 300 & 400 Series Stainless Steel Plates

1. Product Introduction

Our forged stainless steel plates (300 & 400 series) are manufactured through precision forging to deliver superior strength, corrosion resistance, and durability. The forging process refines the grain structure, enhancing mechanical properties compared to conventional rolled plates. These plates are widely used in oil & gas, chemical processing, power generation, and heavy machinery industries.
