AISI 304/L steel and its possible of use

Steel chrome-nickel is one of the most popular species of stainless steel, which has a very good resistance to intergranular corrosion, cracking, and pitting. The symbol Steel AISI 304/L has a special, austenitic structure and low carbon content, and thus gains a very good ductility, pumpability down, weldability and non-magneticism. It is also prone to bending, which speeds up machining.

Modern industries and 1.4307/1.4301 steel stainless steel chrome-nickel steel is a material that before using should be well polished. This material is very susceptible to cold working, but it is very durable. If you need a larger steel strength requirements for selected species with a higher carbon content in the store.

Industries, in which steel 1.4307/1.4301 is essential

Stainless steel 1.4307/1.4301 is used mainly in interior design to create the design and finishes, the installation of drain gases and various substances of a chemical. Use this type of steel for the production of appliances and electronics, everyday devices, agricultural machinery, industrial piping, heat exchangers, silos, mixers, pumps parts distillation boilers. In addition, stainless Steel AISI 304 l is essential in processing meat to build exhaust systems, rotors, medical equipment, separators, cisterns, tanks, valves and the rest of the apparatus (for the production of bolts, flanges, nuts, t-connectors, elbows, bends, compressors, bearings, rings, coolers. Steel, chrome-nickel steel 1.4306 is also used in the chemical and food industries for the production of shafts, springs and gears exposed to smaller load, filters and sieves. It is also used in the automotive industry.

Stages of stainless steel 304/304L

Steel grade AISI 304 l has a reduced carbon content in its composition.  In terms of available forms, this steel grade can be obtained in the form of bars, tubes or plates. Stainless steel with the addition of nitrogen and low carbon content, but high content of chromium and nickel is applicable wherever the species 1.4307, AISI 304 l is not sufficient. In such cases, high resistance to corrosion, so steel chrome-nickel 1.4306 is the perfect choice for the job. Derived grade AISI 304, 1.4301 stainless steel is adapted to cut, which is classified as a stainless steel-cutting with increased amounts of sulphur and carbon. The primary type of steel distinguishes her lack of corrosion resistance able to delivery and who are allergic.

AISI 304H – heat-resistant version of 304 grade

Steel 1.4948 is acid-resistant and stainless steel, the structure is austenitic. Is eligible for fireproof steel and heat resistant. This type of steel is characterized by high work in temperatures (up to 550 ° C). In addition, the composition of this steel compared to the standard types of stainless steel type 304 and 304 l is well thought out and adapted to the material was tough when working at high temperatures.

AISI 304H - One of the most durable steel grades

in terms of mechanical properties, grade of stainless steel AISI 304 h is a very durable material, and suitable for high temperatures. Has a high resistance to creep, and it's all thanks to the REM. In addition, this species is very acid-resistant, therefore does not react to salt, gases and acids.

S30409 - the possibility of using stainless acid-resistant steel

At room temperature specific mechanical properties of stainless steel S30409 is primarily a high tensile strength, which is up to 740 MPa. The yield of this species is above 190 MPa. While the steel during heat treatment increases above 45%. This material is easy and extremely resilient, its modulus of elasticity is as high as 200 GPa. Heat treatment and plastic steel S30409 is primarily on the process utilized in temperatures from 1050 to 1100 °C, together with fast cooling in water or in the air. The next stage is rolling and forging at 1150 to 850 °C with an increase in temperature during treatment increases the strength of the stainless steel S30409. However, the reduction is the yield strength of the material, if the steel is machined at 50-600 °C.

Stainless Steel AISI 304 h and 1.4948 is often chosen by clients to work at high temperatures, and the material is appreciated because of the ease of heat treatment and plastic and durability. For this reason, so fond of this grade of steel is used in so many industries. In addition, the essential fact is that stainless steel is characterized by a high fireproof, so this material is very safe when working in high temperatures or an acidic environment. The biggest advantage of this steel is strength at high temperatures and corrosion resistance, which is why so many industries are happy to use steel S30409 to the individual needs.
