Ordinary carbon steel – General Board, is a steel material. Q represents the yield of this material, behind the 235, refers to the yield value of this material at about 235. And the thickness of the material will increase its yield value decreases. Q235A, Q235B, Q235C, Q235D.

This is a class distinction represents mainly the impact of temperature differs from mine! A, B, C, D, except that, referring to the different impact of their performance in the temperature. Namely:

Q235A level, is not to shock;

Q235B grade is 20 degrees room temperature impact;

Q235C level, is 0 degrees shocks;

Q235D level is -20 degrees shock.

The impact of different temperature, shock value are different. Element content: A, B, C, D sulfur content in descending order; the same phosphorus content of A and B, C, followed by phosphorus content, D phosphorus content of at least Q235 chemical composition of all levels: Q235 points A, B, C, D four (GB700-88)

Its deoxidation method, may be employed F, b, z are represented by boiling steel, flat killed steel, killed steel. Boiling steel is inferior steel deoxidation incomplete, ductility and toughness. Welded structure of this material, when the joint is prone to crack under dynamic loads. Should not work at low temperatures, sometimes produce hardening. In contrast, high quality and uniform killed steel, ductility and toughness are good.

We source only the best materials to make the Stainless Steel EN 1092-1 pn16 Flanges which is why our buyers only receive the best quality flanges.
The Inconel EN 1092-1 flat flange is one of most common fittings used throughout the world. The Alloy 20 EN 1092-1 slip on flange is seen in applications in industries such as oil, gas & mining.
Although the BS4504 or the British standard is now considered to be obsolete it has now been replaced by the  ASTM A350 LF2 EN 1092-1 threaded flange

The Carbon Steel A105 Threaded Flange is a durable pipe fitting designed for secure, leak-proof connections in threaded piping systems without the need for welding. Manufactured from ASTM A105 forged carbon steel, it offers excellent mechanical strength, toughness, and resistance to pressure and wear under moderate temperature conditions. The threaded design allows easy installation and removal, making it ideal for applications where welding is not feasible or on-site welding is restricted. Commonly used in oil and gas, petrochemical, power generation, and construction industries, the A105 Threaded Flange ensures reliable performance, precise alignment, and long-lasting service life in demanding environments.

ASTM A181 grade 1 is a material specification for carbon steel nonstandard as-forged pipeline components such as flanges, pipe fittings, rings, valve component, round bars and many other forging parts, used for industrial piping applications. Its specification covers two classes’ i.e, ASTM A181 class 60 and ASTM A181 class 70. The forging made to this specification are limited to maximum weight of 10000 Lb.

Carbon Steel Weld Neck Raised Face (WNRF) flanges are common fittings in industrial piping systems due to their structural strength and reliability.

We are manufacturers, suppliers and exporters of a range of Ring Type Joint Flanges (RTJ) that are best-in-class. A Ring type joint flange (RTJ) is a machined metallic ring with a deep groove cut into its face. This groove rests a metal ring which gets compressed when the connecting bolts of the flange are tightened. This compression results in a leak-proof, close-fitting seal on the pipe or connection. Carbon Steel Ring type Joint Flanges are spill-proof. They can be manufactured from a number of materials.
