  • comparison of the tensile behavior of a tempered 34crmo4

  • Atmospheric comparison of the tensile behavior of a tempered 34crmo4 refer to storage tanks whose gas or vapor pressure is greater than -0.02MPa but less than 0.1MPa. Metal atmospheric storage tanks made of steel welded on the ground are often used to store petroleum, chemical and other similar liquids. Atmospheric comparison of the tensile behavior of a tempered 34crmo4 usually have a connecting pipe directly connected to the atmosphere, so that the operating pressure in the storage tank does not exceed the design pressure at all times.

What is the tensile strength of a polymer?

As shown in the figure below, the tensile strength of some polymers can rival some ceramics but are no match for even the softest of metals. Tensile strengths of metals/alloys, ceramics, polymers, and composites/fibers.See all results for this questionWhat is the difference between temper and TME?With TME the hardness continues to decrease with higher tempering temperature but the toughness is either flat or decreases slightly. This leads to a lower hardness-toughness balance; it would have been better to temper lower and thus have both higher toughness and hardness.See all results for this questionWhat is 35crmo steel?35CrMo steel is a Chinese alloy steel for engineering purpose, it has high durability and creep strength at high temperature, and low temperature impact toughness is good.See all results for this question

A smooth yielding behavior with absence of sharp yield point was observed in INVESTIGATION OF MICROSTRUCTURES AND 30 minutes-tempered samples. Figure 4 shows the tensile properties of as-quenched and 30 minutes-tempered sample of 440C martensitic stainless steel. It can be clearly seen that the UTS of the as-quenched sample was 517MPa and YS of 124Mpa. However, the UTS and YS of the as-tempered sample are 1044MPa and 368MPa, respectively.Hydrogen damage in 34CrMo4 pressure vessel steel with Various efforts have been made to improve the safety of high-pressure gas cylinders for hydrogen or natural gas with high strength steel liners. Metal liners with high tensile strength have a safety concern, particularly with hydrogen gas or hydrogen generating environments. The hydrogen can permeate into the liner material, and make the material brittle, causing hydrogen damage.

How does tempering affect the ductility of a martensite?

Following that we temper the martensite to allow some of the carbon out and increase the ductility of the martensite; the carbon comes out as very small carbides, a compound of iron and carbon (see What Happens During Tempering? ).See all results for this questionFinite Element Analysis of Tensile Behavior of Ductile comparison of the tensile behavior of a tempered 34crmo4Mar 17, 2010 · The 34CrMo4 material as an excellent alloy has been increasingly applied to the design and manufacture of pressure vessel and piping.
