Elastic deflection at a given geometry depends principally on elastic modulus, section, length and support. Increased yield strength does not mean a proportional increase in stiffness. Set permanent-deformation and in-service position requirements separately, and compare reinforcement, support spacing and load eccentricity.

K-factor and bendability depend on material, supply condition, thickness, orientation, tooling and forming method. A CAD default may be a starting point, but it is not an approval value. Measure actual radius, angle and flange lengths on representative specimens, and retain the associated conditions in the bend table.

Its geometry and assembly results are useful, but cutting route can change edge condition, work hardening, burrs and local ductility. Where edge deformation or fatigue matters, repeat forming and cyclic validation with specimens representative of production shearing.

Overbending may address a repeatable mean angle error. Wall curl, twist or widening variation caused by material or lubrication can require different action. Separate the deformation mode from input variation, then review tool compensation, restraint, process sequence and material control.

Adequate preload is necessary, but thin-sheet indentation, hole distortion or bolt overload may occur first. Evaluate preload and damage using actual lubrication, coating, washer and assembly sequence, and verify contact under load and position after tightening. Do not apply a single generic torque to every combination.

There is no uniform conversion. Salt spray is an artificial, defined exposure; service life depends on environment, coating, geometry, damage and assembled condition. Specify method, exposed regions, duration and acceptance criteria, and consider additional application-representative validation.

That depends on the drawing and functional requirements. Free-state geometry and fit under specified restraint are different characteristics. Evaluate assembly force, induced stress, contact and effects on the mating component, and define support, clamping and acceptance condition in the inspection plan.

Provide matching 2D and 3D revisions, mating components and mounting datums, loads, vibration and environment, material and finish requirements, critical tolerances, tests, quantities and timing. Distinguish unresolved conditions so prototype questions and the production-approval scope can be established efficiently.
