Application of the Pulsed Nd:YAG Laser Welding to

Nov 12, 2018 · In another study , researchers noticed that the welded joint hardness reached the maximum by focusing laser beam toward the AISI 630 stainless steel during laser welding of AISI 630 and AISI 321 Stainless Steels due to the formation of the martensitic-ferritic microstructures. On the other hand, they showed the austenitic microstructure formation in the weld metal when the laser beam Confused about Annealing / Heat Treating Terminology This is accomplished by heating annealed material to a much higher temperature (1950° F/1065°) and quenching as rapidly as possible. This is a hardening treatment, not annealing. To improve toughness, these alloys are then tempered by re-heating in the range of 300° - 1000° F (150° - 530° C).

Hot forming and heat treatment of duplex stainless steels

Hot forming and heat treatment of duplex stainless steels Hot forming Duplex stainless steels show excellent hot formability with relatively low forming loads up to at least 1230°C (2250°F). However, if hot forming takes place at too low a temperature, deformation accumulates in the weaker but less ductile ferrite, which can result in cracking Matchless in Stainless:Welding in a high corrosive Matchless in Stainless:Welding in a high corrosive environment 15th Apr 2019 For materials which need to withstand high corrosive environments super austenitic, duplex, super duplex or nickel alloys are used. The welded joints need to meet the base material

      Stainless Steel - Precipitation Hardening - 1.4542 (17/4

      The most well known precipitation hardening steel is 17-4 PH. The name comes from the additions 17% Chromium and 4% Nickel. It also contains 4% Copper and 0.3% Niobium. 17-4 PH is also known as stainless steel grade 630. The advantage of precipitation hardening steels is that they can be supplied in a solution treated condition, which is Stainless Steel 310/310S (UNS S31000/ UNS S31008)Welding of Stainless Steel 310S Stainless steel grade 310/310S are welded through similar electrodes and filler metals. These are readily weldable through SMAW, GMAW, GTAW and SAW. The preferred electrodes are AWS A5.4 E310-XX and A 5.22 E310T-X and filler metal is AWS A5.9 ER310. Argon is used as a shielding gas.

      • Material TypesWeldabilityFiller AlloysImperfections and DegradationThe alloys can be grouped according to the principal alloying elements. Although there are National and International designations for the alloys, tradenames such as Inconel and Hastelloy, are more commonly used. In terms of their weldability, these alloys can be classified according to the means by which the alloying elements develop the mechanical properties, namely solid solution alloys and precipitation hardened alloys. A distinguishing feature of precipitation hardened alloys is that mechanical properties Specification Sheet:Alloy 625 - Stainless Steel, Nickel alloy, it resists deformation at hot-working temperatures. Hot Forming The hot-working temperature range for Alloy 625 is 1650 2150°F (9001177°C). Heavy working needs to occur as close to 2150°F (1177°C) as possible, while lighter working can take place down to 1700°F (927°C). Hot-working

        Welding Defects - Classification, Causes and Remedies

        Dec 06, 2017 · Hot cracks occur during welding or soon after the completion of welding, It is most likely to occur during the solidification of the molten weld pool. Hot cracks mostly occur in the weld metal but it may occur at the Heat Affected Zone (HAZ) region too. When a hot crack occurs on the weld metal, then it is termed as Solidification Crack and if it occurs in the HAZ then called Liquation crack. Causes of Hot Crack:1. High concentration of residual stress 2. Rapid cooling of the molten weld Stainless Steel Solid Solution Heat Treatment - Zhengzhou Application Fields:Various special steel, high temperature alloy, special properties alloy, nonferrous metals. Especially applicable:1. Workpeice that need to be processed after heat treatment. 2. Eliminate the cold hardening of the molding process. 3. Working after welding.
