　　不锈钢的耐腐蚀性主要取决于它的合金成分(铬、镍、钛、硅、铝、锰、等)和内部的组织结构，起主要作用的是铬元素。铬具有很高的化学稳定性，能在钢表面形成钝化膜，使金属与外界隔离开来，保护钢板不被氧化，增加钢板的抗腐蚀能力。钝化膜破坏后，抗腐蚀性就下降。

　　The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and the internal structure of the alloy, and the main role is chromium. Chromium has high chemical stability, can form a passive film on the steel surface, so that the metal is isolated from the outside, protect the steel plate from oxidation and increase the corrosion resistance of the steel plate. When the passive film is destroyed, the corrosion resistance will decrease.

　　按制法分热轧和冷轧的两种，按钢种的组织特征分为5类:奥氏体型、奥氏体-铁素体型、铁素体型、马氏体型、沉淀硬化型。 要求能承受草酸、硫酸-硫酸铁、硝酸、硝酸-氢氟酸、硫酸-硫酸铜、磷酸、甲酸、乙酸等各种酸的腐蚀，广泛用于化工、食品、医药、造纸、石油、原子能等工业，以及建筑、厨具、餐具、车辆、家用电器各类零部件。

　　There are two kinds of hot rolling and cold rolling according to the method of manufacture. They are divided into 5 types according to the organizational characteristics of steel: austenite type, austenite ferrite type, ferrite type, martensite type and precipitation hardening type. Can withstand oxalic acid, sulfuric acid iron sulfate, nitrate, nitrate acid and hydrofluoric acid, sulfuric acid copper sulfate, phosphoric acid, formic acid and acetic acid and various acid corrosion, widely used in chemical, food, medicine, papermaking, petroleum, atomic energy industry, as well as construction, kitchen utensils, cutlery, household appliances, vehicles of all kinds of parts.

　　不锈钢板表面光洁，有较高的塑性、韧性和机械强度，耐酸、碱性气体、溶液和其他介质的腐蚀。它是一种不容易生锈的合金钢，但不是绝对不生锈。外观:隐形井盖采取独特设计，能完全融入周围环境，井盖与路面浑然一体，不破坏道路的整体美观

　　Stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, corrosion of acid, alkaline gas, solution and other medium. It is an alloy steel which is not easily rusted, but it is not absolutely rusty. Appearance: the hidden manhole cover adopts unique design, and can be completely integrated into the surrounding environment, and the well cover and the road surface are integral, and the whole appearance of the road is not damaged
