SS 347 / 347H Fasteners Manufacturer, Supplier In Mumbai India

Alpha overseas is a well-known manufacturer, exporter & supplier of Stainless Steel 347/347H Fasteners. Both alloys offer high resistance to pitting and general corrosion.

347 Fasteners
The Columbian-stabilized alloy 347 offers exceptional protection against intergranular corrosion at high temperatures. Compared to other stainless steel alloys, stainless steel 347 alloy has somewhat better corrosion resistance in an environment with high oxygen content. Alloy 347 is an austenitic nickel-chromium alloy stabilized with titanium and columbium that was developed to significantly increase the intergranular corrosion resistance of 18-8 type alloys. The alloy should be considered for applications requiring intermittent heating between temperatures of 427°C and 899°C or welding under the circumstances preventing post-weld annealing.

Its features:

  • • High corrosion resistance
  • • good malleability
  • • resistance to surface abrasion
  • • exceptional hardness
  • • accuracy in measurements
  • • long service life

Table Of Contents

In application constructions, stainless steel 347 fasteners are utilized in electronics, electrical, and different sectors. It is commonly used in domestic and industrial applications, including aerospace, large-scale building materials, architectural molding and trimming, and automobile structural applications.

347H Fasteners
The Stainless Steel 347H Fasteners are created from premium raw materials. They are in high demand because of their superior qualities, such as corrosion resistance, low maintenance requirements, standard grade of quality, precise specifications, and wide range. In addition to metals like Ni, Mo, and Cu, this alloy contains chromium in concentrations ranging from 4 to 30 percent. This alloy has excellent creep qualities at high temperatures and is used with heavy welding equipment. The oxidations of this alloy are better. Alloy 347H, which is also UNS S3409 grade and has a carbon content of 0.04 to 0.10, is the higher carbon form of the alloy. It is developed to be more assertive at temperatures up to 1000 degrees Fahrenheit and has superior creep resistance. Concerning the carbon content, it is dual-certified. Only cold working activities can harden them; heat treatment is not an option. These are produced using the standard fabrication procedure. These fasteners are comparable to standard grades and have good general and local corrosion resistance. It is intended to be used in chromium carbide precipitation at temperatures between 427 and 816 degrees Celsius. These are hot formed in the recommended temperature range for other forming procedures, which is between 2100 and 2250 degrees Fahrenheit. To maintain the highest level of corrosion resistance, the fasteners are thoroughly annealed and water quenched after being hot worked. This grade forms easily and is highly shapeable.
