When selecting stainless steel in corrosive environment, in addition to having a detailed understanding of the specific service conditions of stainless steel, the main factors to be considered include: corrosion resistance, strength, toughness and physical properties, processing, formability, resources, price and difficulty of obtaining.Corrosion resistance includes rust resistance and resistance to acid, alkali, salt and other corrosive media, as well as oxidation resistance, vulcanization, chlorination and fluorination at high temperature.

Seawater corrosion resistant materials, and widely used in Marine engineering. However, in practical engineering application, the stainless steel connection, especially the welding area, often appears various corrosion damage, resulting in a great loss. Therefore, in this paper, according to the characteristics of seawater corrosion of stainless steel, the seawater corrosion and anticorrosion mechanism of its weld site were comprehensively analyzed and studied.

Inconel 600 alloy has the following properties.        1. good resistance to corrosion by reducing, oxidizing and nitriding media        2. good resistance to stress corrosion cracking at both room temperature and high temperature        3. good resistance to dry chlorine and hydrogen chloride gas corrosion        4. good mechanical properties at sub-zero, room temperature and high temperature        5.

Corrosion resistanceInternational corrosion resistance of materials according to the annual corrosion rate is divided into three categories, the first category for complete corrosion resistance, the corrosion rate is less than 0.1mm / year, high-quality stainless steel belongs to such materials; the second category for still corrosion resistance, the corrosion rate of 0.1-1.0mm / year, belongs to the general stainless steel; the third category for corrosion resistance, the corrosion rate is greater than 1.0mm per year.Cold rolled descriptionCold rolled: Hot rolled coil is used as raw material,

Description: A002 is an ultra-low carbon Cr19Ni10 stainless steel electrode with titanium calcium type coating.The carbon content of the metallization is less than 0.04%, which has good resistance to intergranular corrosion, and can be used for both AC and DC.Have good operating process performance.Uses: For welding ultra-low carbon Cr1Ni10 stainless steel structures, also for 0G19NThe working temperature of i11Ti is lower than 3000C with corrosion-resistant stainless steel lining structure.

Stainless steel is widely used in petrochemical, atomic energy, light industry, textile, food, household equipment and other fields because of its excellent corrosion resistance, formability, compatibility and toughness in a very wide temperature range.

310 stainless steel is austenitic chromium-nickel stainless steel with good oxidation resistance, corrosion resistance and high temperature resistance. It is often used in light industry, heavy industry, daily necessities and decoration industries.

Stainless steel wire is fabricated from an iron alloy that offers high resistance to corrosion, including staining and rusting, in many environments where spring or galvanized steel wire would typically degrade. Its performance properties, including corrosion resistance and strength, depend on its numerical grade. Type 304 stainless steel wire, also known as 18-8, is a general-purpose material that combines corrosion resistance, weldability, and formability, making it the most commonly used grade of stainless steel.

904L (N08904,14539) super austenitic stainless steel contains 24.0-26.0% nickel, 4.5% molybdenum. 904L super austenitic stainless steel is a low carbon, high nickel, molybdenum austenitic stainless steel, which is a special material introduced from H·S Company in France. It has good activation-passivation transformation ability and excellent corrosion resistance. It has good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid and phosphoric acid.

Completely and infinitely recyclable, stainless steel is the “green material” par excellence. In fact, within the construction sector, its actual recovery rate is close to 100%. Stainless steel is also environmentally neutral and inert, and its longevity ensures it meets the needs of sustainable construction. Furthermore, it does not leach compounds that could modify its composition when in contact with elements like water.In addition to these environmental benefits, stainless steel is also aesthetically appealing, extremely hygienic, easy to maintain, highly durable and offers
