Product Advantages
· Exclusive virgin material smelting eliminates scrap-induced impurities.
· Streamlined, efficient internal production processes ensure a delivery lead time of no more than 30 days for round bar products.
· Proprietary VIM+ESR dual-process technology guarantees ultra-low gas content and refined microstructure in nickel alloys.
· Comprehensive laboratory testing ensures 100% compliance with ASTM and ASME standards.

Production and Inspection Traceability
· From the moment raw materials enter the factory, MTSCO records material grades and MTC (Material Test Certificate) data, verifying material composition via PMI (Positive Material Identification) testing. A dedicated record is created for every batch of raw materials.
· During production, key manufacturing stages including processing status and inspection checkpoints are documented using Process Cards.
· Upon completion, finished products are managed by linking product identification, test results, packaging details, and shipping records. Our comprehensive production record system allows MTSCO to trace critical information from raw material intake to final Delivery.

Material of Alloy 625
Alloy 625 (UNS N06625) is a nickel-chromium-molybdenum alloy with excellent corrosion resistance and high strength. Molybdenum and niobium enhance the material's stability in acidic media, chloride environments, and marine environments, making it suitable for use in chemical equipment and marine engineering structures.
The 30mm thick Alloy 625 Plate is even more suitable for pressure-bearing components, corrosion-resistant liners, structural supports, and large equipment parts.
FAQ
Q1: What tests can you provide for your products?
A1: Common tests include PMI, chemical analysis, mechanical property testing, dimensional inspection, and surface inspection. If required by the customer, we can also cooperate with third-party inspection agencies such as SGS, TUV, and BV.
Q2: Can the 30mm thick Alloy 625 Plate be customized in size?
A2: Yes. MTSCO can confirm the thickness, width, length, surface condition, and cutting requirements according to the order, suitable for equipment manufacturing and engineering project procurement.
Q3: What is the production capacity of your sheet metal factory?
A3: The sheet metal factory covers an area of approximately 6000㎡, with a monthly production capacity of approximately 250 tons, which can support nickel alloy sheet metal project orders and regular industrial procurement needs.
