FAQ (Frequently Asked Questions)

Can Stainless Steel 348H flanges be recycled after use?

Yes, Stainless Steel 348H flanges can be recycled after use. Stainless steel is highly recyclable, with approximately 60-70% of stainless steel being recycled globally. Recycling reduces the need for raw materials, conserves energy, and minimizes environmental impact, making it a sustainable choice for end-of-life products.

Are Stainless Steel 348H flanges suitable for cryogenic applications?

Stainless Steel 348H flanges are generally not recommended for cryogenic applications due to their susceptibility to embrittlement at low temperatures. Alternative stainless steel grades, such as 304L or 316L, are preferred for cryogenic applications due to their superior toughness and resistance to brittleness under extreme cold conditions.

Can Stainless Steel 348H flanges be used for underground applications?

Stainless Steel 348H flanges can be used for underground applications with proper precautions. Adequate corrosion protection measures, such as coatings or cathodic protection, should be employed to mitigate the risk of corrosion from soil moisture and chemical reactions, ensuring long-term durability and performance underground.
