Bolts are chrome molybdenum heat treated steel according to ASTM A193 B7m specification for bolts. The primary alloy components of ASTM A193 Grade B7 bolts are chromium and molybdenum. These ASTM A193 B7 Metric Bolts are manufactured by heat quenching and tempering. Heat treating A193 B7 bolt material helps to develop desired mechanical properties such as increased tensile strength of ASTM A193 B7 hex bolts after heat treatment.

SA335 grade P11 seamless pipe is dimensionally accurate for precision applications, while welded pipe is stronger with high wear and tear properties.

Pipes made of SA335 p11 material are commonly used in a variety of applications in different plants and processes around the world. For example, applications for SA335 grade p11 tubing include power plants, petrochemical plants, refineries, hydrocrackers, cokers, reheat pipelines, distillation, oilfield services, high temperature and ultra-high temperature pipelines, and more.

Chrome molybdenum grades P11, P22, P91 and P92 are used in the power industry. Chromium molybdenum grades P5 and P9 are used in petrochemical refining processes. Chrome molybdenum forged fittings and flanges are available in grades F5, F9, F11, F22, F91, F92. Chrome-molybdenum alloy butt welded pipe fittings are available in WP5, WP9, WP11, WP22, WP91, WP92 grades. F11 and F22 materials comply with NACE-MRO 175.

The alloy steel slides on these elbows can be machined and polished in a stress-relieved condition.

N04400 is a ductile nickel-copper-based alloy consisting primarily of two-thirds nickel and one-third copper. Alloy N04400 is known for its resistance to a variety of corrosive conditions, including alkalis (or acid-like substances), brine, hydrofluoric acid, and sulfuric acid. Other advantages of using this alloy are toughness and high strength over a wide temperature range; it can also be manipulated to be magnetic if desired.

The connection between two pipes can be directly welded together, but it is difficult to connect together without welding. When the connection part have problems, it will be hard to repair. The same problem also happened between pipe and valve connection.

ASTM A182 Stainless Steel Flanges are manufactured per ASME B16.5 150#, 300#, 600#, 900#, 1500#, 2500#.

Chromium Molybdenum Alloy Steel or Chromium Molybdenum, CrMo is an alloy steel used for high temperature and high pressure service. Chromium molybdenum is used in power generation and petrochemical industries for its tensile strength, corrosion resistance and high temperature strength. 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.

ASTM A335 grade P91 tubing contains small amounts of other alloys such as aluminum, niobium, nickel, nitrogen, titanium, vanadium, and zirconium. These pipes are based on the A335 standard, but when forged or drilled, the pipes can also meet the A369 standard. These pipes have a minimum yield strength of 415 MPA and a minimum tensile strength of 585 MPA.

ASTM A193 Grade B7 bolts are made of chrome-molybdenum material with high tensile strength and good elongation properties.

Products made from alloy steel perform far better than those made from carbon steel. Although they are less expensive than stainless steel grades, they are less resistant to corrosion than stainless steel but more resistant than carbon steel pipe.

We play a major role in providing our customers with a high quality range of alloy steel grade 2H lock washers with some great features such as precise dimensions, custom solutions, robustness and more.

The A335 P91 chrome tube composition makes these high mechanical properties possible for the material. P91 steel pipe materials can be normalized and tempered during the production process, and can also be quenched and tempered. These methods increase the strength of the material. Additionally, these pipes are drawn and seamless.

sa335 P5 P5 materials used to make ASTM A335 pipes etc. must meet chemical composition, tensile properties and SA335 P5 hardness requirements. This type of alloy steel pipe is used in applications that require high temperature service. ASTM A335 P5 Pipe Supplier’s Composition, A335 P5 Allowable Stress contains lesser amounts of Nickel and Manganese as they increase the hardness of the pipe.

The flanges can be threaded, ring type joint, lap joint, weld neck or socket welded.

High alloy steel is defined by a high percentage of alloying elements.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

The material can be heat treated to anneal and normalize in air, or quench and temper in polymer or oil. Alloy 4130 has a lower carbon content of 0.28% – 0.33% and slightly higher amounts of other elements. And the material is easy to process. 4140 low alloy steel has a range of 2. 375″ to 12.750″ OD with wall thicknesses ranging from 0.375″ to 1.5″. Alloy 4145 has a slightly higher carbon content than 4140 and 4130 types of pipes.

The flange connection mainly have leakage problem, and the leakage quantity should be controlled within the allowable range of process and environment.

When the carbon content of the a333 gr 6 welded pipe chemistry is lower, the chance of cracking in the welded area is also lower. However, some manufacturers prefer seamless pipes over welded pipes. The reason behind this is that the performance of the a333 gr 6 seamless tube is almost 20% higher than the welded one in high pressure environments.

We warmly welcome our regular and new clients to join us for ASTM Seamless Tee B366 (WP20CB, UNS N08020, Alloy20).

The production of ASME SA182 F9 flanges will be done using alloys with lower carbon content. Reducing the carbon content in these alloys reduces the formation of carbide precipitates. This basically means that alloy steel F9 flanges will no longer be susceptible to intergranular corrosion in the heat affected weld zone.

Flanges are usually welded or threaded. Flange joints are made by bolting two flanges together with a gasket between them to provide a seal.
