不銹鋼:含鉻量為12%以上的鐵基合金稱為不銹鋼,是不銹鋼和耐酸鋼的總稱。不銹鋼是指耐大氣、蒸汽和水等弱腐蝕介質的鋼,而耐酸鋼則是指耐酸、堿、鹽等化學浸蝕性介質腐蝕的鋼,不銹鋼與耐酸鋼在合金化程度上有較大差異,不銹鋼雖然具有不銹性,但并不一定耐酸;而耐酸鋼一般則均具有不銹性,在空氣中或化學腐蝕介質中能夠抵抗腐蝕的一種高合金鋼,不銹鋼是具有美觀的表面和耐腐蝕性能好,不必經過鍍色等表面處理,而發揮不銹鋼所固有的表面性能,使用于多方面的鋼鐵的一種,通常稱為不銹鋼。當前,不銹鋼鑄件在市場上也得到了廣泛應用,今天小編就為大家講解不銹鋼鑄件的四種分類:
Stainless steel: an iron base alloy containing more than 12 percent chromium is called stainless steel and is the general term for stainless steel and acid-resistant steel. Stainless steel is weak corrosion media such as air, steam and water resistance of steel, acid steel is refers to the chemical etching media such as acid, alkali, salt corrosion of steel, stainless steel with acid-resistant steel alloying extent have bigger difference, the stainless steel are not rust, but does not necessarily acid; And acid is commonly have stainless steel, resistant to chemical corrosion medium in the air or corrosion of a high alloy steel, stainless steel is a beautiful surface and corrosion resistant performance is good, need not after surface treatment, such as color of plating and the surface of the stainless steel inherent performance, used in a variety of steel a, often called stainless steel. Today, stainless steel castings are widely used in the market, and today we will cover four categories of stainless steel castings:
