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

q235b是什么材质的钢材

q235b表示屈服点（s）为235MPa的半镇静碳素结构钢。“Q”，代表钢材的屈服点，后面的数字表示屈服点数值，单位是MPa例如Q235表示屈服点（s）为235MPa的碳素结构钢。②必要时钢号后面可标出表示质量等级和脱氧方法的符号。质量等级符号分别为A、B、C、D。脱氧方法符号：F表示沸腾钢；b表示半镇静钢；Z表示镇静钢；TZ表示特殊镇静钢。

钢：

钢是对含碳量质量百分比介于0.02%至2.11%之间的铁碳合金的统称。钢的化学成分可以有很大变化，只含碳元素的钢称为碳素钢（碳钢）或普通钢；在实际生产中，钢往往根据用途的不同含有不同的合金元素，比如：锰、镍、钒等等。人类对钢的应用和研究历史相当悠久，但是直到19世纪贝氏炼钢法发明之前，钢的制取都是一项高成本低效率的工作。如今，钢以其低廉的价格、可靠的性能成为世界上使用最多的材料之一，是建筑业、制造业和人们日常生活中不可或缺的成分。可以说钢是现代社会的物质基础。

q235b是什么材质

Q235B是碳钢的一种代号，表示屈服点为235MPa的B级碳素结构钢。其化学成分主要是碳、硅、锰、硫、磷、铬、镍、铜等。具有一定的伸长率、强度，良好的韧性和铸造性，易于冲压和焊接。

ASTMB367Gr.C2是什么材质

ASTM B367-93(2004) 钛和钛合金铸件 Standard Specification for Titanium and Titanium Alloy Castings

你好,看您对阀门的英文翻译很熟,可以帮我翻译下吗?

size unit下IN NS 应该是美标 英寸，BALL VALVE,CL150,RF,TI ASME B367 GR C2 BODY TI TRIM (PPL) SEATS ，球阀，150磅级，RF法兰，阀体钛材TI ASME B367 GR C2 这个是标准号，阀座TI TRIM (PPL)也是钛材的，(FULL)PORT 全通径，WRENCH CP MSS-SP-72 ASME B16.5，采用手柄操作，手柄的制造、安装遵循MSS-SP-72 ASME B16.5标准，SP-W TVGRAP GASKET 阀体垫片SP-W TVGRAP 这个好像是一种特殊材料编号，需要问工厂核实，GRAP PACKING 石墨填料。REMARK下这些东西应该是一些技术文件代号。

C2是什么材料

SA-556M C2是ASME SA-556M标准中的管式给水加热器用碳锰钢珠光体型钢，分为直管与规定须弯成“U”型的管子。此钢号与我国GB5310中的20MnG、25MnG比较接近。
