Product Description

409, 410 are typical high-strength stainless steel(including chromium) but the temperature resistance is generally only about 500-750. This type of steel has got the chromium content of most stainless steel and can be hence cheap, which makes it ideal for use in environments where there is no rust and semi-slight rust is enabled.

The Type 409 stainless steel was formerly designed for usage in automotive exhaust machine silencers (outside corrosion). 410L stainless steel is commonly used in buses, containers along with cars, and it has been recently used as a framework for LCD screens.

Stainless Steel does not trigger pitting corrosion, rust, or wear. Stainless steel can be one of the most powerful materials in steel materials. Mainly because stainless steel has good corrosion resistance, it empowers structural components to maintain technology integrity. Chromium-containing stainless steel also combines strength along with extensibility, making it straightforward to machine components to fit the wants of architects and structural designers.

Production Process and Feature

409 409L Crystalline characteristics

(1) The Liquid and Solid two-phase Location of 409L Metal Is Extremely small, less than Thirty °C

(2) When the 409L metal begins to crystallize immediately after emptying, the super-cooling amount of the period is so large due to the immediate experience of the top layer of the crystallizer, also at the same period, the surface of the crystallizer promotes nucleation that is non-spontaneous. Hence, the rate of the liquid phase is equally elevated and the formation speed is elevated. Nice equiaxed crystals on the surface. The creation of fine equiaxed grains on the face area is pretty rapid, and also titanium’s carbides really are too limited to precipitate.

Subsequent to the formation of this crystal location that is fine equiaxed, columnar crystals are formed by the steel, however, the 409L metal doesn’t reveal columnar crystals. Due to the narrow temperatures range in the zone, even the 409L metal comes with a smallish part overcooling zone, and also the columnar crystals do not rise. After the formation of this equiaxed crystal place, at an identical period, titanium and carbon possess enough time to liquefy to shape titanium carbide particles to advertise nucleation. The above two reasons create the area to generate equiaxed crystals without any even columnar crystals.

You can find no columnar crystal arrangements in the section, most of which can be equiaxed crystals, but of distinct dimensions. In the pouring process, when the temperature of this slab falls to 1100°C when the carbon material is large, a part of Cr and C kind of carbides, and chromium-depleted areas look around the carbides, along with a small quantity of δ phase can seem.

Inside the steel 2 unique stages of the steel appear at this point, and also the cycle material is 32% to 60% at the blank zone that is plastic. The carbon material of 409L steel is extremely reduced, even if there is certainly a δ stage, the quantity is not small. Therefore, there is absolutely no influence on performance.

There is practically no α → γ stage transition out of high temperatures to reduce temperatures of 409L steel, so the grains are simple to grow upward, a rough ferrite arrangement appears, and also the potency is low. From the casting, once the slab is slowly cut the elbow isn’t hard to appear. The phenomenon impacts manufacturing companies. The principal problem from the crystallization of 409L steel is the reduced performance caused by rough grains. There is practically no γ stage at elevated temperature.


The majority of The prerequisites for usage would be to keep the overall look of their construction for quite a very long moment. When picking exactly the sort of stainless steel for use, the key considerations would be the necessary standards, the temperament of the place air, and also the cleanup approach. But a growing number of purposes are currently hunting for plain water or integrity. For an instance, the side and roof walls of buildings.

In such programs, the fee of construction for the proprietor might possibly become more significant than just aesthetics, and also the outside is not clear. The employment of 304 stainless steel in sterile natural surroundings works nicely. In towns to keep up their lookout doors and rural locations, they have to get washed. In locations along with seriously contaminated locations, the outside may be rusted and cluttered.

Nevertheless, in Order to Get an aesthetic Effect in a setting, nickel-containing stainless steel is demanded. 304 stainless steel is utilized in curtain walls, side walls, and roofs as well as different uses, however, in competitive industrial or marine atmospheres stainless steel is more advised. The benefits of utilizing stainless steel in use now are well understood. You’ll find many design principles for example 316 and 304 stainless steel.

Due to the fact that “duplex” stainless steel 2205 features fantastic resistance to atmospheric corrosion and large tensile strength and elastic durability, this metal can be also contained from the European principles. The truth is that stainless steel is fabricated from full-standard metallic contours and contours, also you can find exceptional contours. Probably the services and products are produced with the sheet and strip metal, and also substances are created by plates, for instance, metal and metal.

In addition, there are around, hexagonal, square, square, and elliptical welded or stainless steel tubes as well as sorts of services and products, which include castings, bars, cables, and profiles.
