Stainless Steel 304 introduction

Stainless steel 304 introduction Stainless steel is an alloy steel based on iron and chromium, supplemented with alloying elements such as nickel, molybdenum, and manganese. The core principle is that chromium in the steel combines with oxygen to form a dense,stable chromium oxide passivation film on the material surface, isolating it from air and moisture and preventing the steel from rusting and corroding.304 stainless steel is an austenitic stainless steel and is the most widely used general-purpose stainless steel material.

Hex Flange Nut Introduction

Hex flange nut is an integrated fastener combining a hex nut and a flange washer face, removing the need for
separate flat washers; its broad flange surface disperses clamping stress, improves anti‑loosening performance, and fits thin or soft workpieces, widely adopted in machinery, automobiles and high‑vibration equipment, available in carbon steel and stainless steel with various surface treatments.
