Quality Management
Every Seather alloy and stainless steel products comply with global standards through strict QC inspections, building a foundation for customer trust.
1.Raw Materials Checking
In order to ensure the quality of the production stainless steel and alloys materials, the incoming acceptance inspections are strictly and carefully inspected by specialized quality inspectors in accordance with the specified inspection content, inspection methods and inspection quantities.
2.Production Quality Checking
In the process of product quality monitoring in the production process, the quality of the produced products is effectively controlled, and inspections are carried out according to the procedures to prevent the outflow of unqualified products and ensure that the final products meet the qualified requirements.
3.Pre-Shipment Inspection
Before the product is shipped, in order to ensure that the shipped product meets the customer’s quality requirements, the product is inspected, and the product that has passed the inspection can be released for shipment. Inspection result records can be provided upon customer request.

14 Gauge Stainless Steel – Everything You Need to Know
When you work with 14 gauge stainless steel, you get a material known for its reliable thickness and strength. The gauge system helps you understand how thick the metal is. Take a look at the standard thickness: Gauge Number Inches MM 14 0.07812 1.984 This thickness makes it a top choice for many tasks. For

Understanding Pressure Ratings for Alloy Flanges (Class 150–2500)
You use pressure ratings to know how much force a flange can take. Each flange class, like Class 150 or Class 2500, has a set pressure and temperature rating. If you pick the wrong flange pressure rating, you could have leaks, breaks, or even total system failures, as shown below: Risk Type Description Leaks Not

Avoiding Cracking in Nickel Alloy Welding: Expert Tips
You can prevent cracks in nickel alloy welding by controlling contamination, managing stress, and following proven procedures. Nickel alloys show high crack sensitivity compared to other metals. You may notice that alloys like Inconel 713C often experience cracking because alloying elements segregate during solidification. A liquid film at grain boundaries, which has poor mechanical strength,

Laser Cutting vs Plasma Cutting: Which Is Better for Nickel Alloys?
When you use nickel alloys, laser cutting often works better than plasma cutting. Laser cutting gives smoother edges and is more exact. High-nickel alloys can get hard fast and need stronger machines than low-alloy steel. You might see tools wear out, need to change tools a lot, or the material may bend. Picking the right

How to Weld Inconel Alloys: Step-by-Step TIG Welding Guide
You can weld Inconel Alloys with TIG by controlling heat and preparing surfaces carefully. Always select Inconel 625 filler for best results. Clean the metal thoroughly to avoid contamination. When welding, watch for issues such as cracking, incomplete fusion, or embrittlement. Common challenges include: Key Takeaways What Is Inconel And Why Weld It Inconel Properties
