今天給各位分享b367-c2是什么材質(zhì)的知識，其中也會對b367c2是什么材質(zhì)進行解釋，現(xiàn)在開始吧！

C2是什么材料

SA-556M C2是ASME SA-556M標準中的管式給水加熱器用碳錳鋼珠光體型鋼，分為直管與規(guī)定須彎成“U”型的管子。此鋼號與我國GB5310中的20MnG、25MnG比較接近。

ASTMB367Gr.C2是什么材質(zhì)

ASTM B367-93(2004) 鈦和鈦合金鑄件 Standard Specification for Titanium and Titanium Alloy Castings

有懂閥門技術(shù)英文用語的來幫幫忙

這還不容易么 看我的翻譯 如果可以你就采納我的答案噢~~~??！

Titanium Valves: 1. General shall not, without permission Party casting welding repair process. 2. Material forged titanium material shall be ASTM B381 Gr. F2, or Gr. F3. Casting titanium material shall be ASTM B367 Gr. C2, or Gr. C3. Titanium components, the maximum iron content of 0.07% and the maximum hydrogen capacity of 60ppm. Casting the mechanical properties of casting residue to comply with ASTM requirements. Stick Titanium Standard ASTM B348 Gr.5. 3. X-ray detection casting is subject to 100% X-ray detection test, based on ASTM E446 Class A, B, C 2-class standards, with no D, E, F. 4. Penetrant testing all the casting in the stress test carried out after the required 100% of the permeability test, in order to avoid casting the cracks, trachoma and so on. 5. Certificate B must provide a detailed mechanical performance testing, physical testing, chemical composition of reports and documents. ? Hastelloy alloy valve 1. Castings Hastelloy Castings Hastelloy C4 and the need to use ASTM A494 Grade CW-2M of the alloy, the largest iron content does not exceed 2%. If you specify the use of Hastelloy C276, Ze Xu using UNS N10276 alloy, mechanical properties required to meet the ASTM minimum requirements. 2. X-ray detection for each casting is subject to ultrasonic or X-ray detection. After each batch and then take 10% of the testing, the nominal diameter greater than or equal 6 "of the body in need of complete testing, greater than or equal 8" in key parts of the body just for testing. -Ray flaw detection test based on ASTM E446 Class A, B, C 2-class standards, with no D, E, F. If you have casting did not meet testing standards be admitted to the batch number of the additional testing. If these two happen again does not meet state testing standards, then take all of the batch for testing. 3. Penetrant testing a batch of each supplier is required to provide penetration testing report at the same time need to provide mechanical tests, physical tests and chemical composition of reports. 4. Certificate B must provide a detailed mechanical performance testing, physical testing, chemical composition of reports and documents. ? dual-phase steel valves: 1. A dual-phase steel all of the components required to meet the ASME V111, Div 1, Appendix 7 requirements. 2. Material Duplex steel castings for example, to comply with ASTM A995 Grade 4A for 2205 alloy, grade 6A for the 2507 alloy. Chemical composition, mechanical properties to meet the requirements of subparagraphs 3 to 5. 3. Chemical composition of the amount of corrosion-resistant duplex steel (PREN) according to the formula: PREN = (Cr wt% + 3.3 Mo wt% + 16 N wt%), calculate the value of not less than the following. 2205 Alloy - 34 2507 Alloy - 40 4. Chemical composition requirements are as follows Material 2205 Alloy 2507 Alloy maximum carbon content of 0.030% 0.030% chromium content of 21.5-23% 24-26% nickel content of 4.5-6.5% 5.5-8.0% Mo content of 2.9 -3.5% nitrogen content of 0.145-0.2% 3.6-4.0% 0.24-0.35% maximum sulfur content of 0.02% 0.02% maximum phosphorus content of 0.03% 0.03% maximum silicon content of 1.0% 0.8% maximum manganese content of 2.0% 1.5% tungsten content of 0.5% maximum 0.8% maximum copper content of 0.5% 0.75% 5. mechanical properties requirements are as follows Material 2205 alloy 2507 alloy minimum tensile strength of 620MPa 700MPa 0.2% deformation deflection (minimum) 450 MPa 550MPa Elongation (2in%) 25min 15min maximum stiffness of 290 BHN (30.5 Rc) 310 BFN 6. The remaining test casting heat treatment, the need to use samples of the following tests. Testing methods and the use of the standard details of the Party should be provided. Tension Test ? ? ? Impact Test hardness testing ? corrosion testing 7. Non-destructive testing, after the final heat treatment in accordance with the following annotation can be seen in non-destructive testing penetration testing X-ray detection range of 100% 100% testing a key component of the valve based on ANSI B16 .34 standard ASME VIII Div 1 App 8 ASME VIII Div 1 App 7 processes ASME VIII Div 1 App 8 ASME VIII Div 1 App 7 acceptance ASME VIII Div 1 App 8 ASME VIII Div 1 App 7
