Should be something like this:

static (inside,outside) tcp 10.46.31.199 80 192.168.46.2 80 netmask 255.255.255.255
access-list outside extended permit tcp any host 192.168.46.2 eq 80

unfortunately I can't test

Can you run a packet tracer and post the output ?

packet-tracer input outside tcp 8.8.8.8 1025 192.168.46.2 80
