What is ASTM A148?
What is ASTM A148?
ASTM A148 is the specification for carbon steel, alloy steel, and stainless steel castings, the grades include 550-270, 80-40, 550-345, 80-50, 620-415, 90-60, 725-585, 105-85, 795-655, 115-95, 895-795, 130-115, 930-860, 135-125, 1305-930, 150-135, 1105-1000, 160-145, 1140-1035, 165-150 etc.
What is ASTM A216 WCB?
A216 WCB is carbon steel castings for valves, flanges, fittings, or other pressure-containing parts for high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by fusion welding.
What is ASTM A27?
ASTM A27 is a specification developed for carbon steel castings for general applications. Often referred to as mild steel, or plain carbon steel, the balance of cost vs. strength of this common form of cast steel makes it desirable for a wide range of uses.
What is the difference between cast steel and carbon steel?
The principal distinction between cast iron and carbon steel is that solid metal contains 2-4% of carbon while carbon steel contains up to 1% of carbon.
What is WCB grade?
“WCB” stands for “Wrought Carbon” with Grade B. Sometimes you can think “C” as casting.
What does WCB stand for in valves?
“WCB” stands for “Wrought Carbon” with Grade B. Sometimes you can think “C” as casting. there are 3 kinds 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.
Is 1030 a chemical composition?
The chemical composition of AISI 1030 carbon steel is outlined in the following table….Chemical Composition.
| Element | Content (%) |
|---|---|
| Manganese, Mn | 0.60-0.90 |
| Carbon, C | 0.270-0.340 |
| Phosphorous, P | ≤ 0.040 |
| Sulfur, S | ≤ 0.050 |
Is cast steel stronger than steel?
The strength of both cast iron and steel is also controversial, as some think steel is stronger than cast iron and others think that iron and steel are same thing, but the truth is that cast iron has a more compressive strength, and steel is more tensile.
Which is stronger forged or cast steel?
Forged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel are altered, conforming to the shape of the part. The advantages of forging include: Generally tougher than alternatives.
Is WCB cast steel?
WCB cast carbon steel (UNS Code J03002) is covered by ASTM A216/A216M standard (ASTM A216/A216M Steel Castings, Carbon, Suitable for Fusion Welding, for High-Temperature Service ), which specification covers carbon steel castings for valves, fittings, flanges and other pressure-containing parts for high temperature …
What is the difference between WCC and 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. A216 LCC is basically the same as A216 WCC except it is charpies impact tested at -46ºC for low temperature service.
