304 stainless steel plate

304L stainless steel plate has much less carbon than 304. 304L is better than 304 in pitting corrosion resistance on welding points or other treated places.

According to the preparation method, it can be divided into hot rolling and cold rolling. According to the structural characteristics of steel grade, it can be divided into 5 categories: austenite ferrite, ferrite, martensite and precipitation hardening. It is required to be able to withstand the corrosion of oxalic acid, sulfuric acid iron sulfate, nitric acid, nitric acid hydrofluoric acid, sulfuric acid copper sulfate, phosphoric acid, formic acid, acetic acid and other acids. It is widely used in chemical industry, food, medicine, papermaking, petroleum, atomic energy and other industries, as well as various parts of buildings, kitchenware, tableware, vehicles and household appliances.

Stainless steel plate has smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion of acid, alkaline gas, solution and other media. It is a kind of alloy steel that is not easy to rust, but it is not absolutely rust free.

Stainless steel plate can be divided into hot rolling and cold rolling according to the manufacturing method, including thin cold plate with thickness of 0.02-4 mm and medium thick plate with thickness of 4.5-100 mm.

In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of various stainless steel plates meet the requirements, the steel plates must undergo heat treatment such as annealing, solution treatment and aging treatment before delivery
