Table Of Content
are low alloy steel tubes that comprised chromium, manganese and molybdenum contents. These alloy of tubes are versatile that possesses reasonable strength and good atmospheric corrosion resistance. The presence of chromium content ensures superior hardness penetration to tubes. Moreover, the molybdenum content enhances excellent high strength and uniform hardness. Furthermore, the tubes feature excellent ductility, toughness, and durability at elevated temperature circumstances. The tubes also demonstrate superior resistance to abrasion, oxidation and general corrosion in tough climatic circumstances. The AISI 4140 Tubes has the superior capability to resist creep in the temperature range up to 1000 degree F. Furthermore it maintains the properties even after exposure at soaring working temperatures. Therefore these tubes wear good resistance in tempered and quenched situations. The forging of these tubes is performed at a temperature of 900-1200 degree C. Moreover these alloys of tubes are heated at 845 degree C and are followed by oil quenching. Before the hardening of this tube, these are normalized through heating at 913 degree C for a long period of time pursued by air cooling. The tubes are hot and cold worked, while the cold working of these tubes is performed by using conventional methods in the annealed circumstances. These tubes are welded by using common welding practices.
Testing & quality inspection-
Our products are passed from strict quality test inspection and testing process that exhibits the workability and quality of the product. Such test is functioned under the supervision of quality authority that strictly checks and inspects each and every material from the receipt of raw material to till its manufacturing. These tests are like-
• Mechanical test
• Pitting resistance test
• Chemical analysis
• Flaring test
• Hardness test
• Flattening test
• Ultrasonic test
• Macro/micro test
• Radiography test
• Hydrostatic test
We provide documentation such as –
• Fumigation certificate
• Quality assurance plan
• Heat treatment charts
• Commercial invoice
• Guarantee letter
• Certificate of origin
• Raw material traceability records
• NABL approved lab test certificates
Packaging of product-
To deliver quality range product to the customers we appropriately pack the products with high-quality packaging material. Thus we pack the tubes in shrink wraps and waterproof plastic that assures great safety from rusting during shipments. Thus each tube is properly packed under the inspection of standard criteria of packaging. Furthermore, the products are also packed in wooden cases, wooden pallets, wooden crates, and wooden boxes and in cartons that ensure to avoid damage during transit. In addition to we pack the products as per the requirements of the patrons.
Marking of product-
After packaging finally, we mark the products with lot no, size, length, and trade mark that ensures easy identification of the product.
