With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
I would like to know where can I find the required maximum hardness test value(HB) of carbon steel(A106-B) after post weld heat treatment. Is this mandatory to carry-out in the preparation of welding procedure, if the design codes are for ASME I, B31.1 and B31.3?

A106 Pipe Specifications A/SA106 NPS 1/4- 30 ASTM A106 seamless pressure pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.
please, could you give us reference from code for Hardness Test acceptance criteria for Base material, HAZ and Weld material for A106 Gr B and C.
Re: ASTM A106 Gr B Hardness Reference value In Reply to Carlos Correia at 05:44 Jul-28-2010. The only hardness in a specification/Code for SA/A-106 Gr. B is the API requirement to keep the pipe weld hardnness below 200 Brinnell. Typical values for E-7018 welds are 180-185 BHN, with the pipe being about 5 points lower.
The Mohs scale hardness of minerals can be commonly found in reference sheets. Mohs hardness is useful in milling. It allows assessment of which kind of mill will best reduce a given product whose hardness is known.
Maximum allowable hardness A106/A516 . Is there any refrence or standard for the maximum allowable hardness for carbon steel welded carbon steel.and findin the hardness PIPE SO HARDNESS. We had a fire in a gas station and soem vessels were exposed for several hours to the fire. Have no idea what the temperature may have been but > 600 degrees C.
ACCEPTANCE CRITERIA FOR WELDS IN ASTM A106 GRADE B STEEL PIPE AND PLATE C. MICHAEL HUDSON,* DAVIS B. WRIGHT, JR.* AND BRIAN N. LEISIHc SUMMARY Several National Consensus Codes contain acceptance criteria for indications in welds.
To convert hardness numbers between measuring methods and scales, see Hardness Number Conversion Chart. Rockwell C Hardness: A designation of hardness, usually of steel or Corrosion Resistant Alloys, measured by pressing a specially shaped indenter against a clean prepared surface with a specific force. The machine making the indention also best sa106b hardness

Steel Boiler Tubes Hot Product-20G,ST45.8,STB42,SA106B HOME > Processing Technoloy > Steel standard In power station construction, boiler tubes and pipes are used in large quantities, especially 20G boiler steel tube , ASTM/ASME boiler tubes for various applications.
1. Introduction. SA-106 Gr. B is a carbonmanganese steel intended for various high temperature service applications such as feed-water reducers in Pressurized Water Reactors (PWR) , liquid ammonia transport from ammonia heater to urea reactor , drain lines in power reactor components , and feeders for carrying out the Primary Heat Transport (PHT) coolant to reactor core .
BS S106 Aerospace Steel Bar. BS S106 aerospace steel bar is a 3% chrome-molybdenum nitriding steel which develops high hardness after heat treatment. It is generally supplied as bright bar in the hardened, tempered and stress relieved condition. The alloy offers excellent wear and abrasion resistance combined with high fatigue strength.
These filler metal suggestions "match" the base metal properties; that is, the yield and tensile strength are expected to meet or exceed the mini-mum specified properties of the steel. Matching filler metal is typically required for complete joint penetration groove welds in tension. However, fil-

When reporting hardness, state the method used, for example, hardness (calc.)or hardness (EDTA). 2340 B. Hardness by Calculation 1. Discussion The preferred method for determining hardness is to compute it from the results of separate determinations of calcium and magnesium. 2. Calculation Hardness, mg equivalent CaCO3/L

Durometer measures the hardness in polymers, elastomers and rubbers. Hardness may be defined as a materials resistance to permanent indentation. The durometer scale was defined by Albert F. Shore, who developed a measurement device called a durometer in the 1920s. A chart showing general hardness comparisons is below.

Best regards - Al By js55 Date 04-14-2008 21:33 You won't be able to tell the difference by looking at it. 333 is a fine grained carbon steel material and comes with specified impact testing, since 333 is for low temp applications.
Hardness; Hardness is the resistance to plastic deformation (e.g., a local dent or scratch). Thus, it is a measure of plastic deformation, as is the tensile strength, so they are well correlated. Historically, it was measured on an empirically scale, determined by the ability of a material to scratch another, diamond being the hardest and talc best sa106b hardness
But S45C Grade Steel is a medium carbon steel, hardened performance is not good, 45 steel can be hardened to HRC42 ~ 46. So if you need to surface hardness, but also hopes to play 45 # steel superior mechanical properties, often 45 # steel surface carburizing, so you can get the required surface hardness.

ASTM A106 pipe is the standard specification for seamless carbon steel pipe for high-temperature service. Most common uses are in refineries and plants when gasses or fluids are transported at high temperatures and pressures.
If it breaks below 15 ft-lbs, it is considered brittle. Our research showed that welds with a hardness value of 315 BHN broke at an average value of 28 ft-lbs, which is significantly higher than the accepted criterion of 15 ft-lbs. Therefore our conclusion was to allow a maximum hardness of 300 BHN for the weld metal.
