Application:The radiant tubes are working at high temperature environment on average:800-1200ºC, Chemical analysis by spectrometer for each heat,eddy current test,pressure test ,thickness test , PT 100%(liquid penetrant test),VI Crystals Free Full-Text Thermochemical Wear of Single The changing chemical composition of the ferrous specimen before and after the test could be surveyed by the energy dispersive X-ray (EDX) analysis, in order to study the influence of correlative factors on the diffusion wear of the carbon atoms in single crystal diamond continuously diffused onto the corrosion surface of the ferrous materials. DIN 1.4021 Stainless Steel X20Cr13 Material Properties Chemical Composition. X20Cr13 material chemical composition is listed in the following table based on cast analysis. Notes:For 1.4021 stainless steel bars, rods, wires, sections, bright products and related semi-finished products, the content of S is 0,030%. A specific range of sulfur content can provide specific performance improvements

EFFECT OF CURRENT INTENSITY ON RESIDUAL STRESS

Q345, plate 2 is martensitic stainless steel 2Cr13, and the filling material of the weld is 2Cr13. The chemical composition of the two materials is shown in Table 1. Keep the voltage constant and change the current in-tensity to change the heat input acting on the unit length of the weld:q w = g/v Where:q w is the effective power of the arc Fatigue failure analysis of rotor compressor blades Oct 01, 2016 · 2. Failure analysis. The 2Cr13 martensitic stainless steel, having a chemical composition of 0.170.22 wt.% C and 1214 wt.% Cr, is commonly used in petroleum industries, as a structural material for blades of air compressor operated under fatigue loading and relatively low corrosion environment [15]. Home - Zhongsheng Steel Co., LtdStainless steel pipe is a kind of hollow round steel, which is widely used in petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and other industrial conveying pipes and mechanical structural parts.In addition, at the same time in bending, torsional strength, light weight, so also widely used in the manufacture of mechanical parts and engineering

The Effect of Plasma Nitriding on the Tribology of

Jul 01, 2010 · A 2Cr13 steel was modified by plasma nitriding. The microstructure, phase composition and microhardness of the nitrided samples were examined. The friction and wear behaviour of the nitrided and unnitrided samples sliding against self-mating under PFPE grease-lubricated conditions in vacuum was investigated on a pin-on-disk type tribometer, with the interactions among the nitrided Thermochemical Wear of Single Crystal Diamond chemical reaction in this atmosphere. (a) (b) Figure 3. Differential thermal analysis (DTA) and thermal gravimetric (TG) curves of the specimens heated in different gas environments; the workpiece material was 2Cr13; the diamond crystallographic plane was (100); the temperature range was from 293 K to 1573 K and 1273 K. (a) Thermodynamic Analysis and Observation of Inclusions in RE The effect of Ce on modifying inclusions of 2Cr13 stainless steel was studied by metallographic examination, SEM and electron spectroscopy. Thermodynamic calculation was used to analyze the formation of RE inclusions in 2Cr13 stainless steel. The result shows that MnS can be entirely replaced by Ce2O2S and CeS that are spherical.
