Manufacturing Process & Quality Control

At Sankalp Alloys, we ensure the highest quality 904L Seamless Pipe through a rigorous manufacturing process and comprehensive quality control:

Raw Material Selection

Our 904L Seamless Pipe production begins with careful selection of premium raw materials. We source high-purity nickel, chromium, molybdenum, and other alloying elements from trusted suppliers with full traceability. Each batch of raw material undergoes thorough chemical analysis to verify composition before entering the production process.

Melting & Refining

The alloying elements are precisely combined in electric arc furnaces under controlled conditions. Advanced refining techniques, including AOD (Argon Oxygen Decarburization) and VOD (Vacuum Oxygen Decarburization), ensure precise control of carbon content and removal of impurities. This results in a homogeneous alloy with consistent properties throughout.

Billet Casting & Conditioning

The molten alloy is cast into solid billets using continuous casting technology. These billets undergo ultrasonic inspection to detect any internal defects before conditioning, where the surface is machined to remove any imperfections that could affect the final product quality.

Hot Working Process

The conditioned billets are heated to optimal forging temperature (approximately 1200°C) and pierced to create a hollow shell. This is followed by hot extrusion or hot rolling processes that form the seamless pipe while maintaining the material's microstructural integrity.

Cold Working & Sizing

For precise dimensional control and enhanced mechanical properties, the hot-worked pipes undergo cold drawing or cold pilgering operations. This process reduces the wall thickness and diameter to exact specifications while improving the surface finish and mechanical strength.

Heat Treatment

All 904L Seamless Pipes undergo solution annealing at temperatures between 1050-1120°C followed by rapid quenching. This critical process ensures the optimal austenitic microstructure, dissolves any precipitates, and maximizes corrosion resistance by bringing alloying elements into solid solution.

Surface Treatment

The pipes undergo pickling in a controlled acid bath to remove any surface oxides formed during heat treatment, followed by passivation to form a protective chromium oxide layer that enhances corrosion resistance. Additional surface treatments such as mechanical polishing or electropolishing are available upon request.

Comprehensive Testing

Every batch of 904L Seamless Pipe undergoes a comprehensive testing regimen including:

• Chemical composition analysis using optical emission spectrometry
• Mechanical testing (tensile, yield strength, elongation, hardness)
• Non-destructive testing (ultrasonic, eddy current)
• Hydrostatic pressure testing
• Corrosion resistance testing (ASTM G48 for pitting resistance)
• Dimensional inspection
• Visual examination
• Positive Material Identification (PMI)

Quality Assurance System

Our manufacturing facilities operate under ISO 9001:2015 certified quality management systems. We maintain comprehensive documentation and traceability throughout the production process, from raw material to finished product. Each pipe is marked with heat number, size, specification, and manufacturer's identification for complete traceability.
