This specification handles an plane-quality, low-alloy metal in the shape of bars, fogings, mechanical tubing, and forging stock. These items are already applied commonly for sections, 3.five inches (89 mm) and under in nominal thickness at time of heat treatment method, requiring a through-hardening metal capable of developing a least hardness of 40 HRC when properly hardened and tempered and likewise for elements of greater thickness necessitating proportionately lower hardness, but utilization isn't restricted to these applications.
This document doesn't specify requirements for unique airplane designs. NOTE: Individual airline or aircraft manufacturers' posted manuals, treatments, or strategies complement the data contained On this doc.
Particular structure and processing methods may well trigger these products and solutions to become vulnerable to worry-corrosion cracking following heat remedy; ARP1110 recommends practices to reduce these ailments.
Usually, a titanium alloy sheet is made to be a coil by very hot rolling that utilizes a tandem mill, and such a coil is Reduce to a predetermined duration for sheet forming. With respect to titanium alloys which have reasonably inadequate workability including α + β style titanium alloys, a so-called "pack rolling" is executed, generally using a reverse mill, in which a titanium alloy slab is filled with carbon steels, for instance, by masking the higher and down sides of slab with carbon steels or by inserting a slab in the carbon metal box ahead of rolling, to ensure that a minimize in temperature in the course of rolling is suppressed and rolling is performed within a significant temperature selection where by the titanium alloy has fairly very good workability.
Rationale: AMS4903C is often a Five Calendar year Evaluate and update of the specification that features the removing of sample dimensions allowance for hydrogen of Table one (included by ASTM E1447), needs arrangement my latest blog post on mechanical home values for material exterior specification ranges (three.
Subject matter to your Guidelines, we undertake to provide you with p/n AMS4902 in good order and in time and with the many required certification of both the manufacturer and our very own.
Sure processing procedures and repair ailments may well bring about this sheet to be subject to stress-corrosion cracking; SAE ARP 982 suggests techniques to minimize this kind of conditions. Product Aspects
