This study aims to determine the effect of rotational speed and forging time on tensile strength and hardness through the friction welding process of stainless steel AISI 310. The research was carried out by friction welding process by using the lathe machine with varying rotational speed (550, 1020 and 1800 rpm), forging time (25, 35, 45 seconds), and welding temperature of 1050°C ± 10°. Axial pressure was obtained through the addition of a hydraulic system to the release head of a lathe machine with a forging pressure of 123.8 N/mm2. Furthermore, the friction welding results were tested mechanically by conducting the tensile and hardness tests. The experimental results showed that the highest tensile strength of the friction welding result of 706,61 N/mm2 was obtained at 1800 rpm and 45 seconds, and this value is lower when compared with raw material (780,25 N/mm2). The highest hardness value (61.5 HRC-A) was located on the welded joint section with 550 rpm of rotational speed and 25 seconds of forging time. The hardness of the parent metal is 69.45 HRC-A. The rotational variation influences the hardness value, the higher the rotational speed will increase the hardness. The longer of forging time will decrease the hardness.

Microstructure and mechanical properties of friction welded and vacuum brazed Ti/AISI 321 stainless steel have been evaluated with various welding conditions. Maximum tensile strength of friction welded joints was approximately 420 MPa with the conditions of 400 MPa of upset pressure (P2) and friction time (t1) within 2.0 s. Maximum tensile strength of brazed joints was acquired under the condition of 900 °C brazing temperature and 5 min. brazing time and showed approximately 275MPa which was about 80% of that of the Ti base metal. Friction welded Ti/AISI 321 joints showed the superior tensile strength than that of brazed Ti/AISI 321 due to thinner intermetallic compound layer.

Metastable Austenitic Stainless Steel

Stainless steels have widespread applications due to their good corrosion resistance, but for certain types of large naval constructions, other requirements are imposed such as high strength and toughness , and modified magnetic characteristics.The magnetic characteristics of a 302 type metastable austenitic stainless steel has been assessed after various cold rolling treatments designed to increase strength by strain inducement of martensite. A grade 817M40 low alloy medium carbon steel was used as a reference material.The metastable austenitic stainless steel after solution treatment possesses a fully austenitic microstructure. However its tensile strength , in the solution treated condition , is low.Cold rolling results in the strain induced transformation to α’- martensite in austenitic matrix and enhances the tensile strength. However , α’-martensite is ferromagnetic , and its introduction to an otherwise fully paramagnetic matrix alters the magnetic response of the material. An example of the mixed martensitic-retained austenitic microstructure obtained after the cold rolling experiment is provided in the SEM micrograph of Figure 1.

Abstract CARPENTER STAINLESS TYPE 405 is a 12% chromium stainless steel that does not harden appreciably. It was designed to allow its use in the as-welded condition. It is particularly desirable for welded applications which require finish machining. It has moderate tensile strength (70,000 psi) in the fully annealed condition and resists corrosion in mild environments. It is used for parts and structures that cannot be annealed after welding. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-395. Producer or source: Carpenter.
