ASTM A403 Abstract
ASTM A403 covers the standard for wrought austenitic stainless steel fittings for pressure piping applications. The material for fittings shall consist of forgings， bars， plates， or seamless or welded tubular products. Forging or shaping operations shall be performed by hammering， pressing， piercing， extruding， upsetting， rolling， bending， fusion welding， machining， or by a combination of two or more of these operations. All fittings shall undergo heat-treatment. Chemical and product analyses shall be performed and shall conform to the required chemical composition in carbon， manganese， phosphorus， sulfur， silicon， chromium， molybdenum， and titanium. Tension test shall be done on the fitting material to determine the tensile properties such as yield strength and tensile strength. Fittings supplied under this specification shall be examined visually for surface discontinuities， surface checks， and mechanical marks.
ASTM A403 Wp316L 该标准涵盖了用于压力管道的锻造奥氏体不锈钢管件。管件材料应包括锻件、棒材、板材或无缝或焊接管状产品。锻造或成型操作应通过锤击、压制、穿孔、挤压、镦粗、轧制、弯曲、熔焊、机加工或两种或两种以上操作的组合进行。所有配件均须经过热处理。
应进行化学和产品分析，碳、锰、磷、硫、硅、铬、钼和钛的化学成分应符合要求。必须对管件材料进行拉伸试验，以确定屈服强度和抗拉强度等拉伸性能。根据本规范供应的管件应进行目测检查，看是否有表面不连续性、表面检查和机械痕迹。
适合 WP 年级的班级
| CR | 耐腐蚀等级。S 至 WU 级不适用。 |
| WP-S | 无缝 |
| WP-W | 焊接，RT 或 UT 所有使用填充金属的管道起始材料焊缝。所有管件制造商的焊缝，A/SA403 第 5.4.3 段除外。 如果用UT代替RT，则必须按照A/SA403第5.6段的要求，对所有焊缝的长度进行100%检测。 |
| WP-WX | 无论是否使用填充金属，都要对所有焊缝进行 RT 检验。 |
| WP-WU | 无论是否使用填充金属，都要对所有焊缝进行 UT 检测。 |
| WP grade-grade-class | 插入牌号（304-304L）和等级（S，W，WX，或 WU）。适用于符合这两个等级的所有化学和物理要求的接头。 |

A403 WP316L Fittings Application
Fittings are used wherever liquids， gases， chemicals and other fluids are created， processed， transported， or used.
Range of industries is very wide， as shown below:
- Energy related
Oil and gas industries， including upstream (exploration and production)， midstream (transportation by ships， pipeline， rail， trucks; storage and wholesale) and downstream (refining into fuels or chemicals; marketing and distribution). Power plants using fossil or nuclear fuels. Geothermal energy for harnessing heat from the earth.
- Food and beverage production
From basic ingredients to elaborate desserts. From milk， to juices and other beverages. Cold chain to keep produce fresh， drinks and frozen foods at a set temperature. Desalination plants to transform seawater into drinking water for arid areas and various tropical islands.
- Pharmaceuticals and biotechproduction
Medicines and vaccines that treat illnesses and help restore bodies and minds to their top conditions.
- Semiconductor manufacturing
Microchips that go into all electronics， including smartphones， tablets， computers， television sets， telecom networks， etc.
- 纸浆和纸张生产
Newsprint， glossy paper， cardboard boxes， books， writing paper， etc.
- Production of construction materials and plastics
