Navstar Steel is a leading manufacturer and supplier of the ASTM A335 P11 Pipe products in various dimensions and types.

What is A335 P11 material?

ASTM A335 P11 Seamless Pipe is made up of a carbon steel that has 415MPa minimum tensile strength 205MPa minimum yield strength. The material has high toughness and high wear and tear resistance. Navstar Steel is a leading manufacturer and supplier of the ASTM A335 P11 Pipe products in various dimensions and types.

What is the difference between P11 and P22 material?

At temperatures above 300 degrees the P11 material’s allowable stress decreases much faster than does P22 materials allowable stress.

Is A335 stainless steel?

ASTM A335 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy-Steel Pipe for high temperature service.

Is P11 low alloy steel?

Low alloy materials are in accordance with the ASTM standards known as P-grades. The most frequently used P-grades are: P5, P9, P11, P22, and P91.

What is A335?

In ASTM international associates defines: “ASTM A335 is the standard specification for seamless Ferritic Alloy-Steel Pipe for High Temperature Service.” This specification covers nominal wall and minimum wall thickness pipe that with alloy material and manufactured in seamless type.

What is low alloy steel pipe?

Pipes that constitute low alloy steels have an alloying content that ranges below 5%. Whereas the alloying content of a high alloy steel would range between 5% to about 50%. Similar to most alloys the working pressure ability of an Alloy Steel Seamless Pipe is about 20% higher than a welded pipe.

What is 9cr steel?

A martensitic steel containing 9% Chromium and 1% Molybdenum is most commonly used in the hardened and tempered condition.

What is the difference between P91 and P92 material?

The chemical elemnet differance lead to that P92 have better physical property. P91 has higher temperature creep fracture strength. The normal temperature strength and high temperature strength of P92 steel are higher than P91 steel.

What grade steel is low alloy?

Low alloy steels are defined When Ni, Cr, Mo, and other alloy elements content consist of less than 10.5% are defined as low alloy steels. The low alloy steels consists alloys with small additions of chrome and nickel up to 11/13Cr steels with 4% nickel.

What is a high-alloy steel?

High-alloy steels are defined by a high percentage of alloying elements. The most common high-alloy steel is stainless steel, which contains at least 12 percent chromium. Stainless steel is generally split into three basic types: martensitic, ferritic, and austenitic.

Which is better D2 or 440C?

The biggest thing that one should consider is if you want stain resistance. 440C is more stain resistant the D2. D2 will darken over time and needs light maintenance. I have done some crazy things in some humid environments without any rust issues.

What is ASTM A335 grade P11 Crome pipe?

The composition of the ASME SA335 Grade P11 Crome Pipe provides it with toughness, strength, hardness, wear resistance, hardenability, hot hardness and corrosion resistance properties. Heat treatment is also possible on the ASTM A335 P11 Alloy Steel Pipe products.

What is the difference between A335 P5 P9 P11 P22 and p91 pipe?

Grade P5, P9, P11, P22 and P91 pipe refer pipe fittings material in ASTM A234 WP5, WP9 ,WP11, WP22 WP91, where flange material in ASTM A182 F5, F9, F11, etc. They have similar chemical composition and mechanical properties. Length: 6 meters, 12 meters or customized. The A335 pipes has a high level of Chromium and Molybdenum presence in it.

What is the chemical composition of A335 pipe?

Our Supply Range for A335 Pipe 1 ASTM A335 Pipe Features. The A335 pipes has a high level of Chromium and Molybdenum presence in it. 2 Chromium – Key Chemical Element for A335 Pipe. Chromium is a key component that is used in the manufacture of stainless steel. 3 A335 Pipe Chemical Composition.

What are the advantages of as P11 grade material?

The chromium content improves the oxidation resistance of the AS P11 Grade Material and the pipes could be used under high oxidizing conditions as well as high temperatures. The elasticity, wear resistance and the strength are due to the molybdenum addition to the pipes.
