Piyush steel specializing in manufacturing the Duplex Steel UNS S31803 Forged Fittings and today we are a top manufacturing firm which offers various types of fittings. Duplex Steel UNS S31803 Forged Fittings which we make are processed by using forging press names as drop forging method. In this method, the pressure is applied on the metal sheets. This makes permanent or plastic deformation and as a result, desired mechanical features are acquired. The forge fitting avoids the cast lose effect which may occur during the smelting process, and this refines the microstructure of the product. Mechanical attributes of these forged fittings are excellent because of the integral metal flow. Also, the forging process makes sure the continuity of fibrous tissue and make a consistent appearance, as well as long service life with better mechanical properties. Duplex steel is made for service in wet corrosive environments. Presence of high alloying element is responsible for improved mechanical properties. This alloy can resist intergranular attack and exposure to an elevated temperature for long. This alloy can be easily fabricated and welded. It can be cold formed very easily because of its higher formability and ductility features. These forged fitting can be exposed to high temperature and pressure without getting elongated or deformed.

Also, Duplex Steel UNS S31803 Forged Fittings we make are resistive to carburization and sulfidation. Also, these fittings can be used in a little oxidizing, nitriding, cementing and thermal process. Also, its find use in the cryogenic temperature.
At our manufacturing firm we are making these forged fitting using advanced technology and proper process to achieve the given attributes and to meet the clients demands. We manufacture it and then make it go through the various test so as to see that product is of high quality and made precisely. We have a team of experts who own enough experience in this field. They know which all tests are to be performed on a certain product. So they carry out testing on the manufactured product as per the guidelines and check the quality of the product. Some of the test conducted is –
• Hardness test
• Positive material test
• Chemical test- spectro analysis
• IGC test
• Micro and macro test
All the product which passes these test is ready for the next process while those product which fails to pass the test because of some errors and mistakes they are excluded. The tested product is taken for the next process which is known as inspection. In this process the product is examined thoroughly through hand and visually. This inspection is done by the third party and after they had inspected a report is made. This inspection report tells that a certain product is manufactured following proper rules and regulations and fit to industrial standards or not.
Once the testing and inspection are completed then the product is ready to be packed. The product is packed as per the demand of the customers. We follow the customer's request and pack the product in special packages is asked to do so. If not then we pack in the standard packaging material like the wooden box or wooden cases. The packages which we make use of are durable and can withstand an extreme environment. So, there is no compromise on the quality of the product. We deliver the product in the best condition, dust, and dirt free as well as damage-free to its destination. Also, if the customer asks us to provide the test certificates along with the ordered product then we provide it to them. Some of the test certificates which we provide are- Inspection report, Manufacture test certificate, lab test report, 100% radiography test certificate, raw material test certificate.
