Composition and properties
Steel AISI 430 ° F (1.4105) is a low-carbon alloy based on iron, ferritic grade, which is characterized by increased wear resistance when working in harsh oxidizing environments, including acids and corrosive gases. Resistance persists at external temperatures up to 850… 900 0 С.
According to the UNC classification, the steel in question includes the following alloying components:
|Percentage||79.2… 83.9||16… 18||Up to 1.3||Up to 1.0|
As inevitable metallurgical impurities, sulfur may be present in the steel (in the amount of 0.15… 0.35%), as well as phosphorus (not more than 0.06%).
The sheet metal rolling of the steel grade under consideration is characterized by the following physico-mechanical parameters:
- Density, g / cm 3 — 7.7;
- Modulus of elasticity, HPa — 220;
- Relative electrical resistance, ohm — 6x10 -10 ;
- Relative elongation,% — 23;
- Heat capacity, J / kgK — 460;
- The coefficient of thermal diffusion, m 2 / s — 7.1.
Compared with the closest analogue — stainless steel S20621, this material has a slightly lower plasticity, which is explained by the absence of nickel and molybdenum in the chemical composition, but by an increased content of manganese. But the steel AISI 430 ° F (1.4105) compares favorably with reduced values of thermal conductivity, which allows blanks obtained from a sheet or tape to resist the sudden temperature changes more successfully.
Steel AISI 430 ° F (1.4105) is fully metallurgically tested before the implementation, the order and procedure of which is stipulated by ASTM A473 (determines the percentage and structure of the main components) and ASTM A939 (determines the influence of temperature, external pressure and ambient air composition on the structural stability of the alloy).
Tape and sheet from this alloy are used in the manufacture of solid and all-welded pipeline structures designed for pumping liquid and gaseous media under high temperature conditions. The material in the annealed condition is well suited to the forming operations of cold sheet punching — bending, drawing, flanging, and the presence of sulfur provides good quality for punching — punching and punching. The presence of sulfur also contributes to a decrease in the intensity of surface corrosion
The nearest domestic analogue of steel AISI 430 ° F (1.4105) is considered to be mild steel 08Х18Н10, characterized by the presence of nickel (up to 10%).Buy sheet and / or tape of steel AISI 430 ° F (1.4105) from Electrovek-Steel is expedient and profitable, since all the offered goods are certified and meet all world quality standards
