304L stainless steel pipe pressure rating chart

7月 15, 2021 カテゴリ: /作成者:

Stainless pipes are ideal in many applications because they have a low resistance to corrosion and high strength that allows them to be used where there are varying amounts of dissolved gas and oil. 304 and 304L stainless steel pipes and tubing are used in almost every field in the world. Making up 50% of stainless steel global usage, 304L stainless steel is currently the second most widely used grade of stainless steel up to 304 steel. It’s a low carbon grade that makes it corrosion resistant and ideal for shipping and industrial use. There are many different characteristics that come from using 304L stainless steel pipes. One of the […]

Nickel Austenitic stainless steel grades

7月 15, 2021 カテゴリ: /作成者:

Nickel is known to be an expensive alloying element and is essential in some applications where both stress corrosion resistance and austenite structure are required. For example, creep resistance is important in high temperature environments, where austenitic stainless steels are needed. Similar to the traditional austenitic stainless steels, the twin boundary is a significant feature of the nickel-rich austenitic stainless steels because of the lower stacking fault energy. Austenitic stainless steels are prone to stress corrosion cracking (SCC). However, the stress corrosion resistance is greatly improved when the nickel content exceeds 20%. The effect of nickel on the stress intensity of stress corrosion threshold (105℃, 22% NaCl aqueous solution) in […]

How to choose the right stainless steel grades?

7月 14, 2021 カテゴリ: /作成者:

Stainless steel is the most popular metal used in kitchenware and other commercial applications because of its durability and resistance to corrosion. However, stainless steels are vulnerable to corrosion if exposed to saltwater and certain chemicals. When purchasing the right stainless steel grades, you should make sure that the following four terms – Corrosion-resistant, mechanical properties, machinability, weldability, surface treatments, that’s depends on the degree of resistance to wear and corrosive solutions encountered during the finishing or seasoning process. Moreover, the type of finishing used and the degree of alloying in the construction determine the composition of the final grade.   Corrosion-resistant Corrosion resistance includes non-rust and acid, alkali, salt and […]

The choice of Stainless steel material for food and beverage industrial

7月 14, 2021 カテゴリ: /作成者:

Most of the challenges facing the use of stainless steel in dairy and other food processing industries are related to heat exchangers and natural surface water such as well water. Like breweries, most food-related industries frequently use hot media that are heated by steam or cooled by water, which is associated with pasteurization and sterilization, and thus often encounter problems such as stress corrosion cracks. In general, food processing does not corrode standard stainless steel such as AISI304 or 316. However, the wide range of processing methods in this industry leads to many different corrosion failures. Such as: Erosion/corrosion in stainless steel milk heat exchangers. Uniform corrosion caused by lactic […]

The choice of Stainless steel material for brewery

7月 12, 2021 カテゴリ: /作成者:

Stainless steel is widely used in the food and beverage industry due to its high temperature resistance, corrosion resistance and hygienic properties. Compared to other areas such as oil and gas production, beer brewing vessels and pipes are regularly cleaned using CIP (site cleaning). In order to obtain the best cleaning results, good surface treatment of containers and pipes is critical. Since the 1960s, industrial beer brewing processes used to manufacture containers and tanks have often used stainless steel AISI 304, or AISI 316, and duplex stainless steel 2205. The corrosion resistance of 2205 stainless steel is comparable to that of AISI 304 while strength is higher, and it is […]

Comparison of 301, 301L, 301LN steel plate

6月 30, 2021 カテゴリ: /作成者:

301 stainless steel is a type of austenitic stainless steel with a high work hardening rate. Its tensile strength can be up to 1300MPa or more. 1/16 hard to full hardening cold-rolled 301 plates are available and maintain sufficient ductility under 1/2 hardening conditions. It can be used for aircraft components, structural components of buildings, especially railway carriage components after rolling or bending. The 3/4 hardening to full hardening cold-rolled sheets should be used for simple component designs that require high wear resistance and elasticity. The 301L and 301LN are low carbon versions and high nitrogen versions of the 301. If better ductility is required or thick section profiles are […]
