1.4113 - aisi 434 pipe, wire, circle

The company Electrocentury-steel offers to buy at the best price in bulk metal-roll of stainless steel AISI 434 (1.4113). The company guarantees the supply pipe and wire made of this steel grade in any range of lengths and diameters, wherein the supplier provides the delivery of goods to any place specified by the customer.

Composition and properties

Stainless steel ferritic AISI 434 (1.4113) differs from the nearest analogues by increased content of titanium element, making the stabilization properties of the material in the process of smelting. Increased percentage of chromium leads to increased resistance against high-temperature corrosion, and the presence of aluminium provides improved raskalennoi steel. Chemical composition of steel is presented in the table:

As inevitable impurities in the smelting, the steel composition there is also sulfur, nitrogen (in an amount of not more than 0.03%) and phosphorus (not more than 0,040%).

Evaluation of corrosion properties of steel

Due to the presence of chromium steel AISI 434 (1.4113) is characterized by high resistance against pitting corrosion when under constant influence of mechanical pressure, high temperature constant presence of active oxidants on the surface of parts is a gradual formation of microwater and cracks. A noticeable amount of titanium retards intergranular corrosion, which contributes to the preservation of the continuity of the surface layers of the parts even at temperatures of 900…950⁰ C. Steel is resistant against the effects on parts of chemically aggressive environments that may be contained in the environment — chlorides, oxides, and oil refinery products.

The ability to machining

Due to reduced carbon content, the steel structure is completely absent iron carbides, which positively affects its plastic characteristics. Therefore, the AISI 434 (1.4113) has a good stampuesit. Pipe made from this steel can be cold-flanging and rolling and bending, including spatial. Wire AISI 434 (1.4113) is characterized by a good capacity for cold heading and drawing without the risk of cracking. During the heat treatment according to the usual modes of quenching, annealing, holidays — the steel becomes austenitic structure and a few hardened, without changing its ferromagnetic targets. When machining on machine tools it is recommended to use a tool of high-speed steels or hard alloys. The steel has good welding ability, as complicating the process of carbides and nitrides in the microstructure of steel no. In the quenching process there is no substantial formation of martensite in the structure, and therefore the level of residual stresses is low. Therefore, the propensity for warping three-dimensional parts after processing are also missing.

Application

Pipe and wire AISI 434 (1.4113) is used as blanks for the production of critical parts fittings oil and gas pipelines, which take place on a continuous pumping of liquid and gaseous chemically aggressive environments at elevated temperatures. The internal stress concentrators do not exist. As the closest analogue of the domestic steel AISI 434 (1.4113) stainless steel is considered 08Х13Т, which is produced according to the norms of GOST 5632. However, in many respects the operating characteristics of steel AISI 434 (1.4113) is significantly higher.

Buy wire and pipe in stainless steel AISI 434 (1.4113) on the proposal of the company Electrocentury-steel is expedient and profitable. Details of constructions and equipment made from this material, will differ high corrosion resistance and heat resistance.
