What’s DSS?

7月 21, 2021 カテゴリ: /作成者:

DSS, the abbreviation of Duplex stainless steel, is a classification of stainless steels composed of two steel with the center one composed of either austenitize or ferric. These are also known as duplex steels since their chemical structure features two distinct phases, both of which are usually represented by martensite respectively. These steels are very useful in applications requiring extreme toughness since the two phases can be applied together at high temperatures and pressures. The duplex stainless steel is able to obtain sufficient hardness in both its austenitic and martensite phases due to the presence of significant amounts of residual austenite. The commonly used DSS grades are S31803, S32750 and […]

Why 201 stainless steel is cheaper than 304?

7月 20, 2021 カテゴリ: /作成者:

201 stainless steel, a relatively inexpensive alternative material to the traditionally 304 stainless steel. The 201 stainless steel sheet does have its advantages over its competitors, it uses a less amount of Cr and nickel content. This leads to less wastage in the making of joints as well as a reduction in the cost of production. In spite of this though the stainless steel sheet loses some of its hardness and ductility when compared to 304 stainless steel. 201 stainless steel sheet has around half the nickel content as that of 304 stainless steel. Instead, tungsten is replaced by various alloy additions of nitrogen and manganese. It is possible that […]

Austenitic Heat resistant stainless steel

7月 20, 2021 カテゴリ: /作成者:

309 and 310 stainless sheets of steel are heat-resistant austenitic steels characterized by high Cr and Ni content. 309S and 310S are their low carbon versions respectively. In oxidizing media, they both have excellent corrosion resistance and high-temperature strength. At room temperature, the matrix microstructure of austenitic stainless steel 310 is pure γ. 310 is also known as “2520 stainless steel” because it contains 25% chromium and 20% nickel, respectively. 310S and 309S are not easy to oxidize at high temperature and are commonly used high-temperature resistance grades. The experimental results show that the oxidation rate of 310 is slow when the temperature is less than 1000℃. As the temperature […]

高温用途向け310S VS 309Sステンレススチールチューブ

2021年7月19日 カテゴリ: /作成者:

310S stainless steel is austenitic chromium-nickel stainless steel, which has good oxidation resistance and corrosion resistance. The high percentage of chromium and nickel content makes it have good creep strength, can work continuously at high temperatures, has good high-temperature resistance. High Ni (Ni), Cr (Cr) content makes it has good oxidation resistance, corrosion resistance, acid and alkali resistance, high-temperature resistance, used in the manufacture of electric furnace tubes, and other occasions. The strength of austenitic stainless steel increases with the increase of carbon content due to its solution strengthening effect. The austenitic stainless steel has high strength and creeps strength at high temperatures due to its face-centered cubic structure, which […]

904Lステンレス鋼の利点

2021年7月19日 カテゴリ: /作成者:

Super austenitic stainless steel 904L (UNS N08904, EN1.4539) is a high alloy Austenitic stainless steel with low carbon content, specially designed for harsh corrosion conditions. It has high chromium content and nickel content, the addition of copper makes it has strong acid resistance especially dilute sulfuric acid, especially high resistance to chloride gap corrosion and stress corrosion cracking, is not easy to appear erosion spots and cracks, pitting resistance is slightly better than other steel. It has good machinability and weldability, in many industrial fields have a wide range of applications: petrochemical vessels and pipelines, such as reactors, etc.; Power plant flue gas desulfurization unit; Seawater treatment plant, seawater heat […]
