Adding nickel adds toughness to the alloy. Similarly adding chromium to chrome moly flanges aids in enhancing other mechanical properties such as temperature strength, hardness, as well as corrosion resistance.

Several ANSI/ ASME standards use materials that are forged or cast to produce Cast AS Blind Flanges.

There are other different types of ASME SA 182 AS Pipe Flanges such as the weld neck flanges and socket weld flanges each specified for a particular role.

Monel 400? sheet is available in thicknesses ranging from .018 to .140″.Butt-weld and forged fittings are available or can be manufactured with short lead times.

Chromium (or chromium) in A335 is an essential element in stainless steel production. Steel products are defined as stainless steels with 12% or more chromium added. Chromium is widely used due to its excellent heat resistance properties and is irreplaceable in terms of resistance to oxidation in high temperature applications.

We are a specialty metals supplier and value-added service provider dedicated to delivering high-quality chrome moly alloy flanges on time and at a competitive price.

The a182 f9 flange is considered a cost saving option. In addition to these properties, astm a182 f9 is reusable and corrosion free.

Chromium molybdenum has a better strength-to-weight ratio than steel, which enables designers to use thinner walled tubing or smaller diameter tubing to reduce overall weight.

We feel proud to introduce ourselves as the well-known manufacturers, exporters and suppliers of Alloy Steel F21 Flanges.

It is almost the same as AISI 4130 chrome-molybdenum alloy steel, but with a slightly higher carbon content. Compared to AISI/ASTM 4130 alloy steel, AISI 4140 steel has a higher carbon content, which provides higher strength and heat treating capability, but also has limited weldability.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

Each tube of the A335 shall be hydrostatically tested. In addition, each tube shall be inspected using non-destructive testing methods in accordance with prescribed practices.

The wider range of flanges are being offered like ASTM A182 F9 slip flange, F9 alloy welded steel socket flange, alloy steel F9 orifice flange, A182 F9 threaded and screwed flange etc. Imperative for the uniqueness of Alloy Steel F9 Socket Weld Flanges is the allotropy of iron-that is, its existence in two crystalline structures.

ASME SA 335 P91 alloy steel pipe also has some excellent properties such as strong construction, precise dimensions, corrosion resistance and more. Our line of ASTM A335 P91 Alloy Steel Pipe is perfectly engineered in tubular form and in a variety of sizes.

Hot rolled 4140 steel also has good fatigue resistance and impact resistance after heat treatment.

ASTM A182 F5 belongs to the American standard Martensite type heat-resistant steel forgings, implementation standard: ASTM A182-2016

Hot rolled 4140 steel bar is a medium carbon alloy steel with high hardenability. This grade is also widely used in forging.

ASTM A320 L7 washers are specially engineered for LOW temperature performance. These fasteners are commonly used for valves, flanges, fittings, and pressure vessels.

ASME SA 335 / ASTM A335 P91 pipe has some great features like fully tested, cost effective, quality certified and more. The ASTM A335 Alloy Steel P91 Pipe offered is manufactured by our experts utilizing the highest quality stainless steel and advanced technology.

This specification covers forged low alloy flanges for use in pressure systems manufactured to specified dimensions or industry standard dimensional specifications.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

Our products are a symbol of constant innovation and superior quality.

ASTM A193 B7 bolts are manufactured to meet numerous specifications and material design properties. More specifically, B7 alloy steel is a high temperature grade of A-193. B7 steel is also a chromium molybdenum steel with a minimum tensile strength of 125ksi.

It is a standard specification defining typical chemical composition, mechanical properties, hardness requirement, preferential heat treatment, product marking, certification and other requirements, suitable for bolting used in pressure vessel service, valves, flanges and fittings. ASTM A193 defines both SI (Metric) and inch-pound units.

Production of low alloy steel materials of different specifications. A335 is a specification for seamless ferritic alloy steel pipes. These alloy steel seamless pipes are used for high temperature service. There are also high alloy steel materials. There are different grades in this material specification. There are grades P1, P2 to P91 and P92. The most commonly used grades are p5, p9, p11, p22, p91 and p91.

Inconel600 is suitable for welding with the same material or other metals by any traditional welding process, such as tungsten electrode inert gas welding, plasma arc welding, manual sub-arc welding, metal inert gas shielded welding, molten arc inert gas shielded welding, and pulsed arc welding. Welding is the preferred solution. When using manual arc welding, it is recommended to use a shielding gas mixed with various components (Ar+He+H2+CO2).
Welding of Incoloy 825 must be carried out in the annealed condition and cleaned with a stainless steel wire brush to remove stains, dust and various markings. When welding the root of the weld, extreme care must be taken (Argon 99.99) to obtain the best quality of the root weld so that the weld does not produce oxides after the root has been welded. Color from the weld heat-affected zone should be removed with a stainless steel brush while the weld area is not cool.

Blind flanges can also be used to seal a nozzle opening on a pressure vessel.
