Neeka Tubes is one of the leading organizations supplying the best quality and highly corrosion-resistant Stainless Steel Flanges to our valued clients. Stainless steel Flanges 304 is mainly known as the most frequent used ‘austenitic stainless steel’. It contains a high amount of chromium (approximately between 18-20 %) and nickel content (between 8 – 10.5 %) .You can also find other significant elements such as carbon, silicone and manganese and iron as a remainder chemical composition. Stainless steel Flanges 304 has great resistance to various range of atmospheric environments and numerous corrosive media. Another positive aspect is the corrosion-resistant in water with up to precisely about 400 mg/L chlorides at atmosphere temperatures ( reduces it to around 150 mg/L at 60°C).
It is the most versatile and flexible stainless steel as it can be used for various kind of household and industrial applications as for example screws, processing equipment’s and food handling, card headers and machinery parts. Additionally, it can also be used in the architectural field for exterior accents e.g water and outdoor space with fire features.
Our Stainless Steel Flanges grade 316 Ring Joint Type is quite ductile and forms easily, which is subject to work hardening during deformation and is subject to chip breaking. Cold working operations will increase the strength and hardness of these Stainless Steel 316L Spectacle Blind Flanges and might leave it slightly magnetic
The Advantages of our Stainless Steel Flanges
- Cost-Effective and Affordable
- Desirable Low-Temperature Properties
- The Controlled Chemical Composition are carefully monitored
- High Resistance and Strength
- Good Formability and Weldability
- Outstanding Response to Hardening by Cold Working
- High Oxidation/Corrision Resistance
The Difference Between 304, 304L and 304H
SS 304, 304L and 304H possess the same nickel and chromium, which means they also share the same corrosion resistance, ease of fabrication and weldability.
Despite that , 304L is known as an ‘ultra carbon stainless steel’ , and the carbon component being down around to 0.03 %. In theory, it is argued that 304L effects of stress corrosion resistance is better than 304, though in practice the effect is not evident or obvious.Key advantages of 304L is that it has excellent welding characteristics and the fact that you don’t require post-weld annealing.
Among the three , 304H has the highest carbon compounds , making it perfect for applications which requires ‘good mechanical properties at elevated temperatures’.Whereas 304L has the lowest carbon compounds, and SS 304 carbon componds is in the middle.
