In order to avoid reduction of impact toughness (temper brittleness), and the corrosion caused by the precipitation of chromium carbides decreased. Martensitic stainless steel with high carbon content than martensitic stainless steel with low carbon content temper brittleness is more susceptible to cold formability, weldability worse. Martensitic stainless steel after tempering is often used to quench tempering 600 to 750 percent, while tempering asked for 1 ~ 4h, get tempered sorbite to improve and enhance the strength and toughness martensitic stainless steel, etc.com. After tempering to be a faster cooling rate, generally using oil cooling temperatures. Crl3 type martensitic stainless steel tempering temperature selection should be based on conditions of use, the requirements of high hardness, high wear resistance of parts usually tempered at 200 to 250 degrees; if requiring high strength and good toughness, generally 600 to 750 degree of tempering. Crl3 type martensitic stainless phase transition temperature of about 800%, the heating temperature exceeds 800% air-cooling can be achieved martensite.
But when the Nickel-Based Alloys Welded Tubes heating temperature is more than 1050% after the strong carbide precipitation during tempering process, so reducing the corrosion resistance of the steel, and therefore crl3 type martensitic stainless steel quenching temperature should be selected.
There are a lot of seamless material, which is one of martensitic stainless steel, stainless steel seamless pipe market is a major production materials martensitic stainless steel, but the production of seamless steel pipe requires a series of processing, technology high complexity, tempered martensitic stainless steel is more important production processes. After tempering cooling faster, on the one hand to avoid temper brittleness, on the other hand tempering slow cooling will produce prop's body, so that the corrosion resistance is lowered.
The preliminary heat treatment can be done in order to prepare for the future organization of surface hardening, nitriding,In general, high carbon martensitic stainless steel welding required before preheating, post weld heat treatment should preferably not be welded. From the viewpoint of corrosion resistance, the use of low-carbon martensitic stainless steel and tempering more favorable.
With the increase of quenching temperature, chromium carbide (Cr23c6) continuous dissolution, hardness and corrosion resistance is likewise rising. Tempering often use 200 ~ 300%: tempering to eliminate internal stress generated during quenching without causing significant changes within the steel structure for the purpose, and maintain high hardness stainless steel parts. Tempering is taking air cooling. Mechanical properties for the purpose. Require high wear resistance, good flexibility and corrosion resistance of the mold, measuring tools, cutting tools and stainless steel springs and other components is commonly used after quenching and tempering. Martensitic stainless steel after quenching and tempering should be avoided in the range of 400 to 600 degrees. Tempering time is 2 ~ 4h, gets tempered martensite., and to improve the workability of the steel

According to metal powder supplier, a lot of steels exist several or even more alloying elements, When several elements coexist on the stainless steel this continuum, decided stainless organization is the sum of the influence of various elements.0007%) of boron in the austenitic stainless steel can make heatstate plasticity be improved; boron to improve the hot strength of steel have good effect, make the hot strength of stainless steel be significantly improved; boron chromium-nickel austenitic stainless steel has a special use in the atomic energy industry. The disadvantage of this type of stainless steel is low mechanical properties, sensitive to intergranular corrosion and stress corrosion, but by the right amount of alloy additives or process measures can improve or eliminate. Performance of the stainless steel except for process factors, mainly depends on the composition of its internal organization, and is the sum of the various alloy elements in the steel constituting the stainless steel tissue. High-chromium ferritic stainless steel was added .
Various elements impact stainless steel u-tube manufacturers on the organization of stainless steel, according to its commonality, to sum up, basically belong to two categories: one is the formation of stable austenite elements, they are carbon, nickel, manganese, nitrogen, copper, the role of carbon and nitrogen is the greatest; the other is formed of the ferrite element, which is a chromium, tungsten, molybdenum, niobium, silicon, titanium, vanadium, aluminum or the like, this type elements form ferrite, such as chromium is to be compared, the role of the other elements were larger than the chromium. The coexistence of these two types of elements in stainless steel, stainless steel tissue depending on the results they influence each other.
Adding the right amount of nickel in the chromium grade stainless steel matrix elements.005% of boron powder, can make the corrosion resistance of steel in boiling 65% acetic acid be improved; added trace If the stable austenite elements role residing in the main aspects, the organization of stainless austenitic-based, rarely even no ferrite; if their role is not yet make austenite at room temperature maintained until then, this unstable austenite upon cooling, martensite transformation occurs, and the steel tissue is martensite; if the ferrite element is formed into the main aspects, steel tissue is mainly in ferrolites..12% or less of carbon) adding 8% nickel, the ideal pure austenite structure is obtained at room temperature, this steel is that people generally said non-magnetic stainless steel.
Chromium-nickel stainless steel such as the same amount of chromium ferritic or martensitic acidproof stainless steel comparison, not only has a higher corrosion resistance, and more important to mention that they have a good cold deformation so that hardening and welding properties, in ambient temperature or low temperature with high plasticity and toughness, and excellent performance of the non-magnetic, etc.0006 to 0. Such as in the ferritic steels of the chromium-containing 18% of the low-carbon . but the stainless steel containing boron will cause reduced ductility and toughness. Source:.Because of adding these elements, resulting in the change of the internal organization of the steel, so that make the steel have special properties. Therefore, the performance of stainless steel, in the final analysis, is mainly determined by the alloy elements
