Product Description

17-4PH Introduction

1-74PH stainless steel is a martensitic precipitation hardening stainless steel. Its domestic brand name is 0Cr17Ni4Cu4Nb. This material is renowned for its high hardness, high strength, and excellent corrosion resistance. It can be hardened through heat treatment, and its typical chemical composition includes elements such as chromium, nickel, copper, and niobium.17-4PH stainless steel is widely used in fields such as aerospace, chemical engineering, petrochemical industry, surgical instruments, flue gasdesulfurization and denitrification in power plants, and environmental dust removal. Surface treatments such as shot peening canimprove its fatigue performance,and electrolytic polishing and chemical oxidation treatments can further enhance its corrosionresistance.

Forming
Grade 17-4 stainless steel can be formed mildly.
Welding
Grade 17-4 stainless steel can be welded using common fusion and resistance welding methods. Oxyacetylene welding method is not preferred for welding this alloy.
Heat Treatment
Grade 17-4 stainless steel is soaked at 1038°C (1900°F) for 30 min and cooled below 16°C (60°F) for complete martensite
transformation in the condition A. The condition A material is treated at 482°C (900°F) for 1 h followed by cooling. Solution
treated material is soaked for 4 h at specific temperature in H925, H1025, H1075, H1100, and H1150 conditions followed by cooling in air. Solution treated material is soaked at 760°C (1400°F) for 2 h in the H1150M condition followed by cooling. It is again heated at620°C (1150°F) for 4 h followed by cooling.
Forging
Grade 17-4 stainless steel is forged at 1010°C (1850°F). Before performing this process, it is soaked at 1177°C (2150°F).
Post-work solution treatment should be performed before final hardening.
Hot Working
Grade 17-4 stainless steel can be hot worked using common processes. It is treated at 1038°C (1900°F).
Post-work solution
treatment should be performed before final hardening.
Cold Working
Grade 17-4 stainless steel can be cold worked using common techniques in spite of its high initial yield strength.
Annealing
Grade 17-4 stainless steel is annealed at 1038°C (1900°F) for 0.5 h followed by cooling rapidly.
Hardening
Grade 17-4 stainless steel has high ductility, and can be formed using all conventional techniques. Powerful equipments are required for forming this alloy because it is stronger than the regular steel. Heavy-duty lubricants are used during cold working.
Applications
Grade 17-4 stainless steel is used in the following applications:
* Nuclear reactor
* Aircraft and gas turbines
* Oil field
* Chemical process components
* Paper mill

SW Tee Introduction

The socket Tee is a type of high-pressure pipe connection accessory that is formed by pressing and forging a steel rod or steel ingot into a blank, and then processed by a lathe. It is mainly used in high-pressure precision fields such as petrochemicals, power, and aerospace. Its production process includes hot pressing forming, radial compression, and branch pipe stretching, which is different from the metal compensation method of the hydraulic bulging process.This accessory is classified into two types based on structure: equal diameter and variable diameter. The specifications range from DN6 to DN100, and the commonly used sizes are DN15 to DN50. The materials include carbon steel (Q235, 20), stainless steel (304, 316L), and alloy steel (15CrMo, 16Mn). The pressure grades include 3000LB, 6000LB, SCH80, etc. The product follows national standards GB/T14383, American standards ASME B16.11, petrochemical standards SH3410, and chemical industry standards HG/T21634. The connection size needs to be distinguished as A/B series according to the standard. The connection methods include socket welding, thread, flange, and welding type, and it is suitable for high-pressure pipeline systems that transport flammable, toxic, or expensive media.
