Gautam tubes are one of the most trusted dealer and supplier of Stainless Steel 304L Flanges. Since long track record in this sector, we have developed expertise in the processing of stainless steel products. We have a big inventory of industrial flanges contain flanges in standard and non standard dimensions. Thus we able are catering to our customer's urgent requirements and end application requirements.
As an ISO accredited company, we manufacture industrial flanges in accordance with national and international standards. We also consider industrial designs to get optimum quality of products. Using trending manufacturing methods and machinery processing of SS flanges tends to precise dimensions and surface finishes, also flanges are surface treated.
Stainless Steel 304L Flanges have oxidation resistance to a maximum temperature of 1650 deg F. it offers continuous service without severe scaling. The maximum temperature for fluctuating temperatures up to 1500 deg F. since 304L is low carbon variant and can frequently be utilized in the welded zones without annealing. Even serve good performance in severely corrosive environments except applications require stress relieving.
These flanges have good welding properties and can be welded by all standard method, however special consideration should be paid to regulate the distance from weld hot cracking. For stress relieving of Stainless Steel 304L Flanges during severe forming and spinning welding is may be followed by annealing operations.
DESCRIPTION
SS 304L flanges have outstanding resistance to corrosive conditions. Machining to work hardening flanges requires heavy feeds and slow feeds. SS flanges have been successfully welded by all resistance and fusion welding operations, however, filler material used is not compulsory. These flanges have to form stronger and cleaner welds which have controlled lower carbon content developed to decrease carbide precipitation at the weld boundaries.
CONCLUSION
The hot working operations should be followed uniformly up to 2100 deg F to 2300 deg F. Rapid cooling is required to attain maximum corrosion resistance properties. Annealing is done between 1850 deg F to 2050 deg F and followed by quenching operations. The heat treatment doesn’t make any sense for hardening. However, cold working operations are preferred methods.
