API 5CT: From raw materials to products before delivery, flattening test, tensile test, impact test, tensile test and other relevant tests shall be conducted. API 5L: The production cost of stainless steel seamless pipe is obviously higher than that of welded pipe due to the micro alloying heating treatment process.

Incoloy alloys have more iron contents than inconel alloys. These alloys show outstanding corrosion resistance, strength, durability, and high-temperature stability.

The term nickel alloy refers to a metal that has nickel as one of its primary elements. Some types of nickel alloys are referred to as superalloys because of their superior oxidation and creep resistance, allowing them to be used at temperatures of more than half their melting points. Nickel alloys can be machined and welded but tend to pose some processing difficulties, as some alloys will work harden during machining, and their high melting points can make them difficult to weld.

Hastelloy is a kind of nickel based alloy. Hastelloy Alloy can be divided into two groups; one contains more molybdenum and the other contains more chromium. They all have excellent resistance to strong oxidizing solutions and high durability in reducing agents. Because of the low carbon content and less carbide precipitation during welding, they also have the ability to resist intergranular corrosion.

Monel refers to a group of nickel alloys that have copper as the main alloying element. In addition to these two primary metals, Monel alloys may also contain small amounts of iron, manganese, carbon, silicon, sulfur, aluminum, and titanium. The specific composition of a Monel alloy depends on its desired properties and applications. In general, Monel alloys are known for their high strength and resistance to corrosion in both fresh and saltwater while also having excellent high and low-temperature resistance.

Incoloy alloys are known for their iron content. Nickel, iron, and chromium are the main and vital ingredients for Incoloy alloys.

Inconel alloys are high-performance nickel/chromium superalloys developed for high temperatures, corrosive environments, and oxidation resistance. They are used in the harshest environments such as: in chemical processing reaction chambers/valves, polymer granule manufacture, military applications, gas turbine components, oil fields, and high-grade marine applications.
Inconel alloys include:
Inconel 600: solid solution reinforcement
Inconel601
Inconel 625: Acid resistance, good weldability. The LCF version is commonly used for bellows.
Inconel 690: Low cobalt content and low resistivity for nuclear applications
Inconel 713C: Precipitation-hardened nickel-chromium base cast alloy Inconel 718: Gamma double prime reinforced with good weldability
Inconel 751: Increased aluminum content to increase fracture strength in the 1600 °F range
Inconel 792: Increased aluminum content to improve high-temperature corrosion performance, especially for gas turbines
Inconel 939: Gamma prime reinforced to improve weldability

201/201LN stainless steel is an austenitic steel. Its primary alloying elements are chromium, nickel, and magnesium. It shows excellent toughness at lower temperatures and is purposed across industries for use in appliances, restaurant equipment, sinks, automotive trim, and more.

202 stainless steel strip has good high temperature resistance.Applications: Architectural decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places.Workability: Cut, Form and Machine with proper equipmen.

Grade 304 is the most commonly used stainless steel. It is an austenitic, corrosion-resistant steel with excellent strength, toughness, fabrication characteristics and weldability. The low carbon version, 304L, may be required for full corrosion resistance when thicker sections are welded.

309 stainless steel has a higher corrosion resistance and strength compared to 304 stainless steel. This product is versatile and known for its high heat treatment capabilities.

Stainless steel 310/310S is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditions through 2000°F. Stainless 310 is often used at cryogenic temperatures, with excellent toughness to -450°F, and low magnetic permeability.
