What is LCC material?

Carbon Steel SA352 LCC is one of the most widely used Carbon Steels in industry. Typically referred to as a cast low temp steel, LCC is the common grade for regular temperature applications for cast steel valves.

What is the difference between WCB and LCB?

LCB grade of castings are tempered after normalizing,while WCB grade are used in normalized conditions. Also while making LCB grade grain refine the metal by adding CaSI, FeSiZretc. This will ensure you getting good impact test results.

What is WCB in valve?

C-Carbon steel; A, B, C stands for the strength of the steel grade from low to high. WCA, WCB, WCC represents carbon steel, ABC represents intensity level, and WCB is commonly used. The pipe material corresponding to WCB is A106B, and the corresponding forging material is A105.

What is the difference between WCB and WCC material?

Carbon steel valves are kept in stock in forged ASTM A105 and it’s cast equivalent ASTM/A216-WCB. ASTM A216 WCC has a slightly higher pressure/ temperature rating than A216 WCB as it has a higher yield strength and a slightly higher manganese content.

What is the difference between A105 and A350 LF2?

A105 and A350-LF2 are standard specifications for forged carbon steel piping components. A105 for ambient and higher-temperature service; A350-LF2 for low-temperature service with Charpy V-Notch impact energy testing.

What material is LF2?

general carbon steel
LF2 grade steel is a general carbon steel which is readily weldable and possesses good impact resistance. The material is capable of through hardening by quenching and tempering on limited sections, but is more commonly supplied in the normalised condition. Machinability is similar to that of mild steel.

What is WCB metal?

WCB stands for “Wrought Carbon” with Grade B. Sometimes you can think “C” as casting. there are 3 kind of Grade A,B & C which define the ductility & tensile strength. Grade B is having very good ductility & tensile strength as compare to Grade A & C. www.castingquality.com.

What is WCB full form?

The Full Form of WCB is Workers Compensation Board.

Is WCB cast or forged?

WCB valves by cast liquid forming that can cause tissue segregation and defects and can be used to cast complex workpieces. The ductility, toughness and other mechanical properties of A105 forged steel valves are higher than WCB castings and can bear greater impact force.

What material is sa105?

ASTM A105 (also known as ASME SA 105) covers seamless forged carbon steel piping components for use in pressure systems at ambient and high-temperature service.
